The 47-year-old Oscar winner and the "Project Runway" host danced the night away at Beacher's Madhouse inside the Hollywood Roosevelt Hotel Wednesday, several sources confirm to Us Weekly.
"They were just having fun by themselves," one insider says of Bullock and Klum, 38. "Nothing scandalous or anything."
According to a second source, the women had been "wanting to meet for awhile."
Despite their A-list status, "no one bothered" either star as they danced together in their booth.
Bullock and Klum aren't the only stars who frequent the Hollywood hotspot: Lauren Conrad, Zac Efron, Paris Hilton, John Stamos, Demi Lovato, Shenae Grimes and Dane Cook have all been spotted partying at Beacher's Madhouse.
