Rihanna is trying her best to make ex-boyfriend Chris Brown regret breaking up with her.

RiRi just posted an extreme close-up shot of her perfect nearly bare ass on Instagram… I say mission accomplished.

During an interview with the Kyle and Jackie O Show on Australia’s 2day FM, Chris Brown confirmed he is no longer dating Rihanna… but is the reason behind the split that is turning heads: “Yeah, Imma do it [that is, celebrate his birthday yesterday] solo, I mean at the end of the day Shawty [Rihanna] doing her own thang, she on the road … it’s always gonna be love … I’m a grown man, just gotta fast forward. I’m always gonna love that person. I can’t be focused on wife-ing someone that young. I need to be the best Chris Brown I can be.”

So someone is too young to be getting married… we’re just not sure who.

It’s back to work for Rihanna after spending the last few days chilling poolside… and she made sure we noticed by sharing a topless snap of her getting made up, only covering her modesty with a white towel.

After celebrating ‘weed day’ with her girl pals, Rihanna decided to slip on a string bikini, relax poolside and post pictures of her ass on Instagram.

Because this is what she does best.

Here are some new pictures of Rihanna (what are they for? I have no idea), the important thing is that she’s braless and is wearing a very see-through top.

The nipple piercing is a nice touch.

Rihanna has posted enough naked pictures online by now that we all know how fine her ass is… so it should come as no surprise that you get a boner from her latest Instagram share.

Rihanna posted this photo along the caption: “Gotcha b***h tip toeing on my marble flo’!!! Sick ass custom Prada boots! Miuccia you RULE!!! Thank you”

Rihanna debuted the video for “Stay” on Monday night… And nobody is talking about the music because she’s naked in it.

The song is among the better received tracks off “Unapologetic” and is one of two recently released singles of the album.

“Unapologetic” is Rihanna’s seventh studio album. You may remember that it was heralded by the Rihanna Plane, a seven-day, seven-country tour that featured Rihanna and 150 increasingly cranky journalists on one chartered plane.

Oh how time changes everything…

Former girlfriend beater Chris Brown posed happily with now official girlfriend Rihanna at last night’s Grammy Awards. The pair, who famously split after Chris attacked her on the way to the Grammy awards in 2011, were all smiles tonight.

Chris’s quick-temper hasn’t changed much though… it got him into trouble again just last week, after he and Frank Ocean were involved in a scuffle at an LA studio. Chris was also involved in an incident with some paparazzi just hours before the Grammy awards…but still was smiling.

On related news: Chris was edged out by Frank Ocean for a Grammy last night, he did clap but appeared to be one of the only people in the first few rows who didn’t stand as Frank accepted his award… at least he didn’t jump him.
