Hayden Panettiere Sheer is Lacey For Letterman

Hayden Panettiere is smokin’ hot in a sheer black Caroline Seikaly dress at the Late Show with David Letterman at New York City’s Ed Sullivan Theater on Monday (July 6).

The 19-year-old actress, who’s in town to promote her new movie I Love You, Beth Cooper, finished off her sexy look with House of Lavande jewels and a fierce pair of Stuart Weitzman shoes.

I Love You, Beth Cooper opens everywhere this Friday, July 10.
