Olivia Wilde, Annie Wersching Redefine Beautiful at FOX’s All Star Party

There is making a winning fashion statement. There is looking hot. And then there was “House” star Olivia Wilde’s jaw-dropping appearance at FOX’s Winter TCA All Star party.

The stunner rocked a tight blue number in one of her best appearance looks to date–hardly an easy feat for a frequent red carpet standout.

“24″ actress Annie Wersching also looked gorgeous at the event. Joining Wilde and Wersching were Dianna Agron, Jayma Mays, Kaylee DeFer, Katee Sackhoff and Lea Michele.
