She's one hot mama! 

Kristen Bell looked better than ever (and most of the other stars) in a gorgeous Pamella Roland gown at the Critics' Choice Awards on Jan. 17 in Santa Monica. While the new mom is no stranger to rocking a red carpet, the sexy halter dress with keyhole opening that showcased her slim post-baby body is a departure from her traditional style — and we're loving it!

"It's a little wild for me, but I'm kind of excited about it. I thought maybe, 'Unexpected New Mom' would be the title of the look," the House of Lies star (and new wife to Dax Shepard) told Us Weekly.

Indeed, Bell, 33, was a welcome sight in her black gown amidst the many brightly colored dresses of the night worn by Julia Louis-Dreyfus, Amy Adams, and more.

While the glamorous dress showed off Bell's tiny waist and toned arms, her hair and makeup added a hint of rock 'n' roll glamour to her style.

Her blonde hair was slicked on the sides, given volume at the top and crown, and pulled into a high, tight bun. The mom of Lincoln, 10 months, also played up her eyes with lots of black eyeliner and a hint of a cat-eye.
