Look Who Popped Up At Brit-Brit's Concert?!

Britney Spears brought her Circus tour to a close in North America on Sunday with her final performance in Sin City.
She had some famous faces in the audience (Miley Cyrus was one of them), but it was the one who surprised her on-stage that caught her attention.
During her performance of Breathe On Me, Lance Bass surprisingly appeared on-stage, giving her what looks like a well deserved laugh.
Oh that Lance Bass! What a tool guy!
