TRICK HIS RIDE

Forget baby steps! Fifteen years away from getting his driver's license, and Sean's already got a mini Cadillac Escalade to practice on while his mother gets busy recording new tracks. "I've been going to the studio lately, and we've been trying out different nannies, but it's hard," Britney says of being a working mom. "It's personal because this person is with your child every day. I'm so torn right now."
