Katie Holmes strikes a pretty pose in her first ad as the new face of Ann Taylor. She joined her The Romantics costars for a J. Crew photo shoot last year, but this time the February Elle cover girl is all on her own looking pretty in navy blue. Katie spoke of her new role to WWD saying, "I applaud women who are doing their best to be the best versions of themselves and who are working really hard. And I’m glad that there is a store like Ann Taylor that can offer amazing styles for the many different roles that women play." She also gushed a bit about her own love of the brand, telling Hollywood Reporter, "I've been a fan of Ann Taylor since I was a young girl — I grew up loving the clothes. I'm thrilled to be a part of a brand I believe in." Katie's miniseries The Kennedys may never air in the US, but most of you would love to watch her take on iconic Jackie O as the actress also continues to cement her stylish place in the fashion world.

Natalie Portman was glowing, bronzed, and wearing a playful cutout Vena Cava dress and Aldo shoes when she hit the red carpet at tonight's No Strings Attached premiere in LA.

She'll be decked out twice again this weekend, first at the Critics Choice Awards, where we'll be broadcasting live from the arrivals line, and again on Sunday at the Golden Globes. Natalie is happy and calm as she takes on award season while expecting her first baby.

Scott Speedman seemed to be in high spirits and was looking hot last night at the NYC premiere of his latest film, Barney's Version. He was joined by costars Paul Giamatti and the lovely Minnie Driver, who spiced up the red carpet in a strapless gold and black minidress. Paul and Scott play friends in the quirky tale of an unlucky-in-love character named Barney. The film was among the honorees showcased at the Toronto Film Festival and made Buzz's list of January's must-see movies. Paul's in the market of working with extremely good-looking castmates as he preps to start filming The Ides of March this Spring with Hollywood's hottest bachelors Ryan Gosling and George Clooney. Not to be outdone by Paul, Scott also recently signed on to another handsome ensemble, joining Channing Tatum and Rachel McAdams on their upcoming drama, The Vow.

AnnaLynne McCord was dressed in full Na'vi gear on the LA set of 90210 yesterday. She wore head to toe blue paint to portray a sexy version of the Avatar character for a scene where Naomi tries to impress a geeky guy she meets online. AnnaLynne had a break from filming to spend the holidays overseas in Cambodia while the hit show took a midseason break, and you can test your knowledge of what's already gone down before the whole West Beverly High crew returns to the small screen on Jan. 24.

Britney Spears arrived in pink at a dance studio in LA this afternoon. She debuted her highly anticipated new single, "Hold It Against Me," on Ryan Seacrest's radio show to rave reviews yesterday, and the song shattered iTunes records as it reached No. 1 within hours of its midnight release. We got a glimpse at the sexy cover art this week as she prepped for the big day and got fans excited over Twitter. She went back online this morning to thank all of her supporters, and if the response to her latest new music is any indication, her next album is sure to be a success. She's working hard on her moves as well, though the rumor that she'll be opening the Grammys is apparently false.
