You gossip mavens probably already know that Ms. Spears performed lip-synced a brief but dance-intensive 15 minute set in San Diego and LA earlier this week, under the name "the M+Ms." Well, guess who's listed on the marquee at the Red Devil Lounge for Monday night?

Tickets for the M+Ms go on sale tomorrow at 6 p.m. If it actually is Brit, here's the song list she's gone through (in identical order) at her two previous shows: Baby One More Time, I'm a Slave 4 U, Breathe on Me (complete with strip dance), Do Somethin', and Toxic. Dang, how does her wig stay on through all that?

We love that picture of bald Britney whaling on the SUV with the green umbrella!
