RiRi is the queen of the nightlife scene these days!

Rihanna hit up Eden nightclub in Hollywood with some friends last night, and the singer showed off her lighter new 'do, which she paired with bold bright red lips and a completely see-thru black minidress. That's one way of getting Chris Brown's attention!

The Barbadian beauty has been on the grind preparing for her upcoming world tour, so we don't blame her for cutting loose during her night on the town. After all, when you work as hard as this pop star, wouldn't you want to be entitled to a night off?

She shines bright like a diamond!

This is certainly a bold move for any Hollywood star!

Celebs like Kristen Stewart and Nicole Kidman dared to go bare for W magazine's "Brightest Stars" issue, and only these actresses' can make no makeup look sexy!

Shot by famed photographer Juergen Teller, the pics show Hollywood's leading ladies in their most stripped down form, and although the Aussie Paperboy actress looks almost better fresh-faced, the same cannot be said about K-Stew unfortunately!

Inside the pages of the glossy, the On The Road actress talks about her nude scenes in the film, and how being undressed on camera isn't quite as torturous as pretending to have rhythm during a dance scene.

"Everyone asks about the nude scenes in On the Road, but I also had to dance, and dancing is harder than being naked. My character, Marylou, is so exuberant, and I had five minutes to do something that showed she was sort of like the craziest motherf***er around. By the end, I was as red as a fire truck. I was holding onto Garrett [Hedlund] because I was going to fall over. I almost passed out every single time," she confessed.

Oh la la!

Va-va-va-voom!

Jennifer Lopez and her much younger beau Casper Smart sizzled at the Vegas promotional screening of Parker.

In the flick, JLo plays a real estate agent who's going through some personal shiz. Good thing she has a strong shoulder to lean on with co-star Jason Statham.

The sexy Latina's Kaufman Franco gown is to die for!

Demi Moore left Chateau Marmont in Hollywood alone, but earlier in the day, Ashton Kutcher's ex was surrounded by a crowd of A-list celebs! Watch the video below.

Demi joined Nicole Kidman, Reese Witherspoon, Andy Garcia, Amy Adams, Ben Affleck and Matt Damon for a surprise appearance on Jimmy Kimmel Live. Damon took over the show as host while Kimmel sat tied up with "Loser" written across his head.

What a great way to bring even more attention to his earlier time slot!

As for 50-year-old Demi ... sucks to be heading home so late all alone. Perhaps she'll find love again soon!

Another one bites the dust!

Marc Anthony has called it quits with his Venezuelan model girlfriend Shannon de Lima, his rep confirms to E! News.

The couple, who had been dating a little more than a year, gave no reason for their breakup. This was the Latin singer's first major relationship since his split with ex-wife Jennifer Lopez.

Don't count on a reconciliation, though!

J.Lo is happily in love with boyfriend Casper Smart, who has been a constant companion of the former American Idol judge since they revealed their relationship last year.

We doubt Mr. Anthony will have trouble finding another sweetie!

Wow ... Taylor Swift is workin' that sexy body of hers!

The 23-year-old country songstress walked the blue carpet at the 40 Principales Awards in Madrid looking gorgeous in a white Kaufman Franco dress and Christian Louboutins.

Swift took home the award for Best International Artist. She Tweeted:

"Tonight was my first time at the 40 Principales Awards in Madrid and it was amazing. Thanks to the fans for the International Artist Award."

Taylor was fun and flirty in short tap pants and a red sequined top for her performance. Harry Styles MUST be missing this!

A couple's gotta stay caffeinated!

On Thursday, Ashton Kutcher and Mila Kunis got their java fix as the two went to grab a couple cups of Joe at a Coffee Bean in Studio City.

The former co-stars looked pretty casual during their run, with Mila going make-up free on their brief down time. She's been filming non-stop and has recently expressed interest in starring in the upcoming Fifty Shades of Grey flick while her Two and a Half Men beau's new film jOBS has been picking up steam in time for it's premiere on the final day of the 2013 Sundance Film Festival.

Good to see that even a busy Hollywood couple can make time for the little things!

Should we call her G.I. Jenna?

A pregnant Jenna Dewan-Tatum kept things moving on Thursday as she was out and about in Los Angeles sporting some workout attire with an army jacket over it. Could be a new style!

The 32-year-old actress showed that even expecting moms can do it all as she hit up a yoga class, stopped by Whole Foods to refuel and finished things up with a little spa treatment at a nail salon. Seems like it was all in a day's work for Channing Tatum's baby(ies)!
