Britney Live (Sorta) at Mansion!
If you don't have MTV and you want to see Britney Spears lip synch through one of her songs -- have no fear! TMZ has some video for you!
Britney "performed" at Mansion nightclub last night in Miami Beach, Fla., busting out some old and new moves while she "sang" for an enthusiastic crowd.
Milli Vanilli eat your heart out.
