There's no sitting at home and moping for this girl!

Newly single Katie Holmes took advantage of her newfound freedom last night by attending the 9th Annual Style Awards in NYC, and the Jack & Jill actress dressed to impress in a cream knee length skirt with black embroidery and a sleek black button down. The ex Mrs. Tom Cruise really knows her fashion!

In her first public appearance since her split from the A-list actor, the 33-year-old hit the stage to present an award to style icon Carolina Herrera. A style icon in her own right, Holmes is preparing to show her ready-to-wear collection Holmes & Yang at New York Fashion Week on September 12.

The brunette beauty recently admitted that it takes a thick skin to break into the cutthroat fashion industry. "When you go in and show your clothing, you think that they're going to buy the whole collection. And when they don't, you're like, 'What do you mean? It all goes together. So what do we do with this?' So that was new, but I think that's kind of a life thing - 'What, you don't want all of me?'" she told WWD.

We can't wait to see the threads Katie!

Rihanna showed off a super short and sexy 'do at the Staples Center while rehearsing for the MTV Music Video Awards.

We haven't seen the gorgeous songstress wearing this much clothing in awhile, but the "Where Have You Been" singer can pull off just about any look ... even jeans and sneakers.

Can't wait to see which sizzling outfit she'll be wearing on stage tonight for the big show.

We'll be watching!

Mariah Carey performed at the 2012 NFL Kick-Off Concert at the Rockefeller Center in New York City on Wednesday evening, and the 42-year-old pop diva turned heads when she took the stage.

Not only did she hit the high notes when she sang her new single "Triumphant (Get 'Em)," but she caught everyone's attention in a short and sexy strapless black dress. Hubby Nick Canon was on hand to support his ladylove, and after Mariah's performance, No Doubt took the stage, and Queen Latifah finished off the evening with a rendition of the National Anthem.

So who else will be sitting alongside Mariah on the judging panel for the upcoming season of American Idol? That remains to be seen, as she is still the only celebrity who has officially signed on to the hit Fox singing competition...

C'mon, when she looks this good, how can we talk smack about her outfit?

Gwen Stefani and her No Doubt bandmates were spotted leaving their NYC hotel on Wednesday evening, and the 42-year-old singer/fashionista flashed our photographers a gorgeous smile (and a peek at her bra!) as she made her way to their show at the Rockefeller Center. After performing "Settle Down," Gwen's bandmate Gabrial McNair ‏tweeted, "Well, that was a lot of fun. Thanks to the fans for your big support. It was nice rocking out with you NYC!"

No Doubt is releasing their highly anticipated sixth album, Push and Shove on September 25, and they just announced yesterday that they will be doing 6 concerts at the Gibson Amphitheatre in Los Angeles in late November and early December. Can't wait!

Who knew Hermione Granger would turn out to be such a hottie!?

Emma Watson was snapped outside of the Ed Sullivan Theatre in New York City following her appearance on The Late Show with David Letterman last night, and the 22-year-old actress looked absolutely amazing in a black and white pantsuit.

Emma is currently busy promoting The Perks of Being a Wallflower, where she plays Sam in the coming of age adaptation of Stephen Chbosky's best-selling book. "Making this movie was so pivotal for me because I realized I do really want to be an actress, which wasn't something I fully knew, since Harry Potter was such a singular experience," Emma tells the new issue of Glamour mag.

When asked about her style these days, Emma adds, "When I was younger, I used to do it all myself, but I've had to get help because it's gotten to a stage where I can't show up in my Converses or whatever I bought from high street. Just practically, these gowns are ridiculous. You're being photographed from every angle, so not only do you have to consider how the thing looks, but whether you're going to be able to sit in it and whether people are going to be able to see up your skirt."

Kristen Stewart must not be feeling very 'Irie' about her broken finger!

The Twilight star was wearing a cast of sorts on her left middle finger as she jetting out of LAX today, headed for the Toronto Film Festival.

Ugh! ... This is certainly going to be an impediment when she's looking for the appropriate answer to journalists' questions about cheating on Robert Pattinson and her illicit love affair with Snow White and the Huntsman director Rupert Sanders!!!

Pamela Anderson's body may be ready for Dancing With the Stars: All-Stars, but the 45-year-old former Baywatch babe isn't quite camera ready.

But since she's just going to rehearsals, we don't blame her for ditching the heavy makeup. No doubt, the Playboy Playmate is sweating up a storm.

We can't wait to see Pam and her sexy legs cha-cha across the dance floor.

Work it, girl!

The Duchess of Cambridge's little sister is looking mighty American in her red, white, and blues!

Pippa Middleton is currently enjoying her stay in New York City, and her visit has kicked the rumor mill into overdrive! The British socialite was spotted spending time with hotelier Andre Balazs over Labor Day Weekend, and although she's supposedly in town for business meetings, speculation is rampant there might be other reasons for her journey across the pond.

The 28-year-old brunette beauty was allegedly apartment hunting in the city with a realtor today, as the pair were spotted cabbing to various buildings. The party planner is expected to spend more time in the States as she promotes her new book, Celebrate: A Year of Festivities for Families and Friends.

Is romance also a motivating factor in her rumored move?

Pippa attended the U.S Open yesterday, where she was seated next to Spencer Vegosen, the son of the U.S Tennis Association. "There was definite chemistry between the pair," a source told the New York Post. The duo were later spotted enjoying a seafood dinner at Le Bernardin restaurant.

We hope the rumors are true!
