Miley Cyrus is too busy to party in the USA.
OK, maybe it's not all work and no play at the sorority spy flick. Miley said she rocked out at a wild wrap party with costar Jeremy Piven.
"There was this band Groovy 7, they were amazing," she says. "They actually let me and Jeremy [play], so he got up on the drums and we played 'I Love Rock and Roll' and that was pretty hilarious, that was a good time."
