The 25-year-old managed to sex up a "traditional" look by rockin' a jean-on-jean matching midriff-baring, low-cut top that left little to the imagination.
Given the Bajan beauty's affinity for sexy snapshots, it's no surprise to see Rihanna pics of any racy getup, but this getup in particular is just ... wow.
She captioned the pic: "Jocking my $h*t!!! #rihverisland"
Well, that about sums things up perfectly right there.
Chris Brown's ex is, of course, shouting out to her clothing line collaboration with River Island, which, apparently, specializes in barely there tops.
Rihanna is known to be a big fan of Topshop ... or was, anyway.
She is often seen browsing their clothing at the Oxford Street store or palling around with Topshop heiress Chloe Green ... but she's not happy with them now.
She's suing the British retailer for $5 million. Over this:
Rihanna always finds a way to up the Instagram ante.
In her latest self portrait, the sexy singer rocks robe and sunglasses, not to mention a short blonde wig, with the caption "Just a casual day at the office."
The newly-single star recently took to Twitter and Instagram to show off some Canadian tuxedo side boob, showing Chris Brown exactly what he's missing.
For better or worse. Karrueche might win that round.
Sometimes, a girl's gotta wear shorts so small that her thong hangs out. Pretty standard. That image is one that could be quickly seared into male brains.
Which is probably her intent, though the extent to which Chris Brown has one is unclear. Rihanna, who's filming her new video, loves to cause a stir.
She didn't name any names, but we're gonna guess one Instagram follower in particular was the intended audience for this image. Or maybe two.
In a Tweet that has since been deleted, the effed up actress randomly SLAMMED Rihanna, writing of the singer and her infamous run-in with Chris Brown's fists:
"@rihanna Chris Brown beat you because you're not pretty enough."
Bynes added that "no one wants to be your lover so you call everyone and their mother that I almost named my dog Rihanna."
Ummm... zing?
Rihanna replied to Amanda's unexplained diss with one simple, awesome sentence:
And soon afterward Bynes was at it again, sending another Tweet that she quickly erased, but not before it etched its way on to the Internet for all to see:
"@rihanna unlike ur fugly faced self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty u know it!"
RiRi is yet to write back to this profound insult, but there is a silver lining to this unexpected feud: it can distract Rihanna from Brown moving back in with Karrueche Tran.
According to documents obtained by TMZ, Greenidge explains that a rep for RiRi Woo - a produced endorsed by the singer - applied the lipstick to her upper lip and told her to spread it around.
The next day?
"My whole lip was irritated and hugely swollen," Greenidge says, adding that she went to a doctor and was diagnosed with the disease.
Naturally, it could only have come from the fact that many others in attendance at the concert had also sampled the lipstick. Or so Greenidge argues.
She is suing M.A.C. Cosmetics, Inc. for unspecified damages.
Complex magazine has named Rihanna the Hottest Woman in the World right now, as this publication clearly disagrees with Maxim awarding the same honor to Cyrus last month.
No reasons were given for the top ranking, at least not in word form. But this photo of RiRi checking The Hollywood Gossip says it all, doesn't it?
Even after he beat her senseless in 2009, the couple remained close, and he even dumped girlfriend Karrueche Tran to get back with her last summer.
The rekindled romance with Chris Brown fizzled, however, and Karrueche is back in the picture, reportedly leaving Rihanna despondent and confused.
Thus the rumor that the pop star has begun - or will soon begin - a 12-step program to help get over "the love of her life" and his impact on her life.
"Rihanna is desperately in love with Chris. It's like she's obsessed with him and, although he's told her it's over, she just can't get over him," a source says.
"After talking it through at length with a psychotherapist," the insider adds, "Rihanna's now doing a 12-step program to get rid of her demons."
What does that entail in this case, exactly? The alleged program is said to have "a format similar" to that used for alcohol and drug rehabilitation.
Chris Brown's love is her drug, people. And a seductive, powerful one at that. So potent it might even make you lash out and hit a fan with a microphone.
Anyway, the Ranch's Women's Love and Sex Addiction Treatment Program, in Tennessee, is said to help women who have issues along these lines.
Might Rihanna benefit from this, given her history of "attracting troubled, addicted, abusive or otherwise emotionally unavailable partners?"
Rumor or not, it does make you wonder. The facility, interestingly, offers "a number of treatments including counseling and equine therapy."
For a different kind of equine therapy, allow us to recommend watching Kate Upton topless on a horse. That will put anyone in a good mood.
Anybody need a toke? Rihanna has enough to go around.
For an entire nightclub worth of people, it would appear.
The marijuana-loving singer took to Instagram on Saturday in Amsterdam (doesn't it figure), where this sort of thing is not only legal, but encouraged:
We see countless Rihanna photos featuring her smoking as it is, so imagine how much fun she'll have in a place where she doesn't have to rein it in?
She captioned one of them "#LegalizeIt" ... then upped the THC-filled ante by posing for a few pics with MASSIVE blunts and a lighter in each hand.
The U.S. has not #legalizedit across the board, but Colorado and Washington have, and you can get a medicinal card in California like it's no thing.
Or so we've heard. Yeah, that's it.
Again, this isn't Ri-Ri's first declaration of her love for the herb. Nor will it be the last. But outside of the 20th day of April, it may be the most egregious.
Rihanna is paying tribute yet again to her late grandmother Clara "Dolly" Braithwaite, posing a touching photo and note on the anniversary of her death.
The singer writes on her Instagram, along with the following picture:
"Today marks one year since you crossed the bridge! Still you never left... I can still remember your laugh, and I miss it, I miss the sound of your voice."
"I miss the way you danced and got so happy when you heard music, I miss doing your makeup and taking your pictures, I miss the way you looked right at me."
"I miss looking back at you, that proud look on your face!"
"Never did I think it could be this soon, but I'm happy you're in Heaven, laughing and dancing with the Angels! Dolly you are my precious Angel!"
"I love you beyond what words can describe!"
"I just miss you Gran Gran! #Dolly #FirstAnniversary"
Clad in a tight black tank and pink skirt at Paris Fashion Week, Rihanna had a starry run-in with another no-holds-barred celebrity, Jennifer Lawrence!
"Bumped into the extraordinary Jennifer Lawrence at dinner! #Paris" the singer tweeted, along with an Instagram shot of the two posing together.
While not quite on par with Miley Cyrus Twerking (what is), the video posted by Rih's BFF Melissa Forde shows her gettin' FREAKY to A$AP Rocky's "F**kin' Problems."
Naturally, she's doin' her thing to Drake's verse on the hip-hop hit.
One can't help but wonder how Chris Brown might react, seeing as ...
Not surprisingly, Rihanna has topped the list of the Top 50 Most Influential Celebrities on the Web, a study put together by Zimbio determined.
Image may be NSFW. Clik here to view.
In order to be considered, a celebs has to be active on both Twitter and Facebook, be primarily famous in the U.S., and have an individual account.
In other words, no bands, and no brands.
Given Rihanna's Twitter, Facebook and Instagram presence, it's no surprise that she edged Justin Bieber, Miley Cyrus and Britney Spears for the crown.
Google+ and YouTube accounts, as well as scores on Klout, were also used to determine which famous figures have the most dominant digital footprints.
The always interactive Rihanna and Justin Bieber top the list overall, but Zimbio has also broken down the stats with the infographic shown above.
Britney is most likely to follow you back on Twitter, while Miley is the most active at Tweeting each day. And Twerking, but that wasn't a part of the formula.
Lady Gaga leads in YouTube videos, Kim Kardashian in money earned per Tweet (stunner), and President Obama in most likely to follow a porn company.
Just kidding. But he totally did that at least once.
Chris Brown‘s new single, “Can’t Say No,” and its intensely suggestive lyrics have the masses wondering if it's an ode to Rihanna ... or Karrueche Tran.
In the leaked track, a slow jam/love ballad, the 24-year-old R&B star calls a woman "irresistible" because "without you girl, the sun don’t shine.”
“Girl without you it’s hard to breathe, it’s like you are my air. Made a man out of me, ’cause your love, it sets me free, and when I need you you’re there."
Perhaps the biggest hint that it's about Rihanna, not Karrueche, is the lyric, “we’re in love all over again," which has to mean their renewed romance, right?
Of course, the couple split again recently. But he sings, “Cause you changed my life, I’ll never walk away” and “in love forever, always be together.”
Chris broke up with Karrueche to get back with Rihanna last year, then went very public with their renewed romance ... which fizzled this spring.
Since then, he's been seen out and about with Tran again. Obviously. But is she just someone who fills the void while he yearns for his true love?
Sources say that Chris Brown and RIhanna considered each other soul mates and lovers for life and that they both envisioned marriage and family together.
Their careers and personalities have made that unlikely, at least in the short term, but both are believed to still love and respect each other, intensely.
While Chris certainly has love and respect for Karrueche, can she really “put a spell” on him on that level? Or will she always be his second option?
Tell us below ... and if you were Chris (or any single guy for that matter) which of these hot tickets would you rather have as your shorty?
