Britney Shooting New Music Video?!

Rumor has it Britney is already shooting a new music video for Circus!

Bryan, Britney's brother, was seen onset today with Britney's backup dancers. The dancers were dressed in very Circus-like costumes, which included a few of Britney's old backup dancers from the "Dream Within A Dream" tour & "The Onyx Hotel" tour, as well as some of the newer ones including head-choreographer Andre Fuentes.

Sounds like the second single is "Circus," with rumored director Francis Lawrence ("I'm A Slave 4 U")!
