Just bust a move!
After running over to Hayden Panettiere, the People’s Choice Awards host looked the Nashville star up and down and exclaimed, “Gorgeous! Gorgeous!” about her blush, tiered strapless gown, an onlooker tells PEOPLE.
Grabbing each other’s hands, Cuoco and Panettiere were engulfed in “animated conversation,” but things got even more fun once the deejay played Madonna’s “Like a Prayer.”
Cuoco and pals hit the dance floor, where she clapped, swayed and “was twirled by a male,” the source adds. Later when Bell Biv Devoe’s 1990 hit “Poison” was played, Cuoco held up her long dress while showing off a few more moves.
The actress was dancing so much that she “left the party with her heels in hand!” the source adds.
