Happy 24th Birthday, Rihanna!

To think that we've witnessed this Barbados beauty win multiple music awards, dye her hair almost every color in our crayon box and land her own fashion TV show...they just grow up so fast.

Wait, is "grow up" the right term? Anyhoo...

Yesterday marks Rihanna's 24th birthday!

How will the edgy singer celebrate?

We really don't know what there is left to do, seeing as Ri-Ri has been celebrating her big day for a while now, but she can surely think of something. We also don't know if Chris Brown will be part of the festivities, but even if he is, they're "just friends" so we really shouldn't care either way.

What we do know (or at least assume) is that there will be cake. And who doesn't love cake?! (Speaking of birthday cake, did you hear about her possible collabo with Brown on her song?)

Whatever shenanigans this li'l lady gets into, we hope it's a birthday to remember.

HAWT; Who is the most desirable woman of 2012?

Nobody fills out a dress like Sofia Vergara ... so it's no surprise that the almost cartoonishly curvy "Modern Family" actress is the top hottie on AskMen's 11th Annual "Top 99 Most Desirable Women" list.

What happened to last year's winner, Blake Lively? The "Gossip Girl" is not even in the top nine this year, slipping down to the lowly #31 spot.

In fact, the top nine ladies may surprise you in more ways than one. For starters, who the heck is the #2 spot-holder, Kate Upton? Rooney Mara is pretty, but she needs to smile more ... and eat a sandwich. And we love Nicki Minaj, but is she really the fifth most desirable woman in the world?

From Sofia to Nicki to ninth place-holder Rihanna, let us know: Who is the most desirable woman of 2012?

BLAST FROM THE PAST; Rihanna Rings in the New Year With a Flash—of Her Pierced Nipple!

What's a Rihanna sighting without a little scandal?

The controversy-courting pop star, who made headlines back in September when she was kicked off an Irish farm for baring too much skin during a raunchy music video shoot, wasn't shy about showing off her assets yet again when she hit Diddy's star-studded New Year's Eve bash in Miami this weekend.

Ri-Ri rocked a seemingly demure black Tom Ford long-sleeve, knee-length dress with a sexy keyhole neckline, black pointy-toe pumps and diva-red pout.

Pretty tame for this "S&M" singer's standards, right?

But the 23-year-old Barbadian beauty opted not to wear a bra and ended up flashing her pierced nipple for the cameras.

Was it an unintentional or a wardrobe malfunction?

We're guessing no, since this isn't the first time Rihanna's dared to bare her chest in public.

Way to stay, er, consistent in 2012, babe.

Rihanna, Cheryl Cole to record duet this week

Cheryl Cole and Rihanna will reportedly record a duet together this week.

The pair have been rumoured to be planning a collaboration for some time and Rihanna is said to have agreed to record a "party anthem" with Cole for the Girls Aloud singer's upcoming third album.

Fresh reports have since claimed that the singers will meet at an LA studio later in the week to work on the project.

"Cheryl's flown to LA to put the finishing touches to her album and is due to meet Rihanna to record their duet," a source told the Daily Star Sunday.

 "It's been a long time coming and something both their management teams have been trying to arrange. But with their busy schedules and Rihanna's tour dates, they haven't been able to until now."

Cole is also said to be in talks to record collaborations with Eminem and Nicki Minaj for her new album, which was recently described as her best yet.

Cole's new single, which is rumoured to be co-written by herself and Taio Cruz, is apparently due for release in March.

Rihanna 'won't let go of Chris Brown'

Rihanna has apparently been contacting ex-boyfriend Chris Brown relentlessly in the hope of reuniting.

The 'Talk That Talk' singer has reportedly started calling and texting Brown, even going so far as to spend time with him as he records new music.

"Not only has she initiated a Twitter conversation with Chris for all to see, but she has gone to see him," a source told Life & Style.

"She stopped by his studio recently - twice. She's also calling and texting him a lot. She won't let go."

The insider went on to claim that Brown has not returned Rihanna's advances, adding: "She's trying to break up Chris and his girlfriend, Karrueche [Tran]. Chris is happy, but Rihanna keeps playing her games to make trouble. It's become an issue."

Though she previously insisted that she would never speak to Brown again, Rihanna was recently warned against reuniting with the R&B singer.

She has vowed to "find a man" and quit smoking in 2012.

Rihanna Skips People's Choice Awards 2012 for NBA Game

Despite being nominated for two kudos, Rihanna was a no-show at the 38th annual People's Choice Awards. It was later uncovered that the "Only Girl (In the World)" hitmaker actually spent the night watching a basketball game right across the street from where the awards show took place.

On Wednesday, January 11 night, the 23-year-old singer was photographed sitting courtside at the Los Angeles' Staples Center to catch a match between Los Angeles Clippers and Miami Heat. Trading a glam-up look for a casual one, she opted to wear sweatshirt and a pair of jeans with a snapback cap.

Riri was nominated for Favorite Pop Artist and Favorite R&B Artist at this year's PCAs, which ceremony took place at the Nokia Theatre in Los Angeles. The ex-girlfriend of Chris Brown lost the former trophy to "Skyscraper" singer Demi Lovato, but nailed the latter one.

The "We Found Love" singer wasn't the only one blowing off the awards ceremony though. Her best friend Katy Perry, who has just separated from husband Russell Brand, was also absent from the event. She, however, turned out to be the biggest winner of the night by scoring four kudos, including Favorite Female Artist and Favorite Song of the Year.
