Sexy Stars: Julianne Hough and Kate Hudson flash their abs

Blonde bombshells Julianne Hough and Kate Hudson served up seriously sexy style this week in two ab-baring ensembles.

Julianne Hough, 27, wowed in casual look that most people wouldn't dare step out in. The dancer-turned-actress rocked low-rise yoga pants and a sports bra at the launch event for MPG Activewear at Lord & Taylor -- and, no surprise here, totally pulled it off.

Kate Hudson, 36, flashed her own toned tummy in a chic black-and-white two-piece set comprised of a bandeau top and high-waisted, wide-legged pants. Slicked-back hair and red lips completed her knockout look. Get her look for less.

But it wasn't all about the skin this week. Amy Adams, 41, turned heads in a gorgeous blue custom Antonio Berardi mermaid gown with a ruffle detail. Similar here.
