Rihanna

It's Friday, Friday and we used up all our Rebecca Black jokes already. Today (Aug. 16) in the celebrity Twitter-sphere, stars threw shade at one another, made us laugh at their witticisms and quoted 'Mean Girls.' All in all, not a bad start to the weekend.

Rihanna adored her grandmother, and when she passed, the Bajan beauty went all out in funeral arrangements for her grandmother. Except she allegedly didn't go all out in actually paying for them. Oops!

Rihanna makes no secret that she's not a role model -- she says so herself all the time. But the hard-partying singer may be partying with hard substances as well. A new video surfaced that led many members of the Bajan beauty's beloved Navy to worry that she's actually using cocaine.

Rihanna has been busy suing British clothing retailer Topshop for using her likeness without permission, and even though UK law says you can't copyright your own image, she still won big.

Rihanna has a few purposes for her Instagram account: topless selfies, weed smoking selfies and hairstyle selfies. She took to the photosharing app once more last night to indulge in the latter breed of self portrait, showing off a style that may have been last seen on a blind girl in Lionel Richie's 'Hello' video.

There was once a time when pop star Katy Perry would stick her neck out for her celebrity pals, but then being a nice person who helped others ended up being all for naught -- so she's given up her righteous ways. Thanks a lot, Rihanna. Way to ruin it for everyone.

Rihanna has apparently been pulling a Lindsay Lohan, read: blowing off court depositions. But now a judge has had enough, fining her an amount that may be larger than your annual income.

In Rihanna's mind (and on top of her head), grey is the new black. The singer has taken a pause from posting topless shots on her Instagram feed to instead share shots of her new dye job: a thoroughly granny shade of grey.

Rihanna needs to work on her tardiness. The 'Stay' singer was late for yet another concert, this time in Manchester, U.K. -- and the Brits didn't take lightly to her transgression -- and that fury led to a food fight.

Don't even try talking to Meg Ryan or Rihanna. Ever.

Jay-Z is a busy guy. He's got Presidents of the United States to text. He doesn't have time for Chris Brown and Rihanna's adolescent drama. And he said so quite plainly.

What happens when you're the most famous singer on the planet and you get wasted at a music festival? The same thing that happens to the rest of us: You get kicked out. Rihanna learned that the hard way this weekend.

Black and white will always be in style, but right now, geometric, bold black and white prints are trending. Rihanna donned a kaleidoscopic black and white two-piece ensemble, while Kaley Cuoco topped skinny jeans with a flowy tank. There are many ways to wear this trend, so you just have to pick what's right for you.

Seems Chris Brown thinks he and his on-again-off-again ex-girlfriend Rihanna are cool. But based on one of her recent Instagram posts, they are anything but.

We're used to Rihanna going topless all over Instagram, but her sheer Chanel shirtdress, worn to the house's show during Paris Fashion Week, was the equivalent of her online photo exploits. In other words, despite the classy label, it was a tad too tacky and trashy, two "T" words that you don't want associated with you during the fashion industry's biggest time of the year.

Rihanna and Jennifer Lawrence are not two names you'd normally expect to find in the same sentence -- except when RiRi just so happens to run into J. Law during Paris Fashion Week.

This weekend, Rihanna posted selfies while smoking two ginormous blunts. No surprise there -- she's a known pal of Mary Jane's. She also poses topless on the regular (and doesn't hesitate to slip a bottomless shot that angers her mother into the mix every now and then). But it seems Daily Mail journalist Liz Jones doesn't much appreciate Rih's shenanigans, and she took the pop tart to task for be

It seemed some of that Chris Brown aggression may have rubbed off on Rihanna on Sunday, June 16, when she whacked a fan with her mic mid-song during a concert.

Shades are an essential part of any hot weather wardrobe, and black sunnies are all the rage this year. Celebs are taking care to choose an array of statement shapes that flatter their faces, like Rihanna's retro cat-eyed sunglasses or Kourtney Kardashian's thick, rectangular pair.

It's good to be Rihanna. The singer and topless wonder of the world (well, except Ireland) invaded the Balmain showroom, posting a bunch of pics of herself modeling the French design house's wares looking like a kid in a fashion candy store.
