X17 caught some video of Britney Spears in Miami (well, I figure it has to be in Miami, because lord knows no one's dressing like that around L.A. these days...), jamming out to her demo tape in her car. You can catch a little portion of two different songs. Honestly, they don't sound as awful as they'd been rumored to be, but, like I said, it's just a short sample.
Update: Well, everyone else is saying these pics are from Santa Monica. I thought Brit was in Miami this week, and, seriously, it is SO COLD in L.A. lately, I cannot believe she is wearing this outfit, but whatever.
