Cate Blanchett went "blanc" with this Spring 2013 Givenchy gown at "The Hobbit" Royal Premiere in London. The backless, side-slit number was balanced out by long sleeves and complemented with a slicked back hair style.

We just can't get enough of Anne Hathaway these days! Her "Les Miserables" fashion crusades continued in London during the movie musical's London premiere last week in this short Altuzarra number.

But she really hit us with the wow factor in New York! Here, Hathaway turned to Tom Ford for a sexy red-carpet look. Her body-skimming gown with high volume at the top was amped up even more with her custom Tom Ford gladiator boots. And get this — they're vegan. Bespoke booties for the beauty!

Way to show some skin, Mrs. Timberlake. Newlywed Jessica Biel opted for an ethereal Atelier Versace gown for the premiere of her new romantic comedy, "Playing for Keeps."

You know you're a style star when a line creates something custom, just for you. That's exactly what Salvatore Ferragamo did for Jessica Alba during its 75 anniversary fête in London.

Kristen Stewart is continuing her style star ascent, and if she keeps dressing like this — in a look from Jason Wu Spring 2013 — she'll be the top of everyone's best dressed lists in no time.

"GIRLS" star Alison Williams is no stranger to the limelight, thanks to her HBO status, and we just love that she's not afraid to have a little fun on the red carpet. This sequined, zig-zagged midi dress from L'Wren Scott did just the trick.

Just because it's cold outside doesn't mean you have to stay away from color. Silver screen starlet Olivia Munn proved just that at the Giorgio Armani beauty luncheon in L.A. with this bright Emporio Armani dress, Christian Louboutin stilettos, and Giorgio Armani clutch.

Zoe Saldana showcased her support — and style — at the 22nd Annual Beat The Odds Awards for the Children's Defense Fund in Los Angeles on December 6th. Her aubergine Giambattista Valli dress, Gucci shoes, and Lanvin clutch worked wonderfully at the philanthropic affair.

Joining Saldana at the Children's Defense Fund ceremony was Reese Witherspoon in a this Elie Saab Resort 2013 LBD. We spy peplum!
