Sexy Stars: Reese Witherspoon plays peekaboo and Halle Berry dazzles in lace

Hollywood's biggest names stole the spotlight this week in the fashion department!

Reese Witherspoon lead the sexy pack with a jaw-dropping black dress with a keyhole neckline. The "Walk The Line" star's peekaboo top was seriously sexy and she polished off her stylish look with her hair swept back in a pretty updo.

Halle Berry, who attended the same Tiffany event as Witherspoon, was also a looker in a black, lace blouse that showed off a hint of her décolletage. The sheer look was the perfect juxtaposition to her buttoned up black pantsuit.

Kate Hudson turned heads this week in a silky, champagne-colored dress with a plunging neckline. She buddied up to both Halle and Reese during a night out in Beverly Hills.

Sofia Vergara, Taraji P. Henson, and more stars were also knockouts. Check out all of Hollywood's hottest stars this week.
