The Circus Starring Britney Spears closed out seven months of performances with a surprise lap dance for former boy bander Lance Bass in Las Vegas Sunday night.

During Brit’s 90-minute pop extravaganza at Mandalay Bay, the *NSYNC star Lance Bass brought on stage for a lap dance from his pop star pal. “My good friend Lance surprised me on stage last night for ‘Breathe On Me.’” Britney wrote in a blog post on her website Monday. “It was soooo funny! Good to see you Lance!”

Teen queen Miley Cyrus and one-time Spice Girl Melanie Brown were in attendance for Britney’s Saturday Vegas show.
