Britney Spears cruised around Santa Monica last night -- with Sean P. and Jayden James gripping each other in the backseat as their popwreck mom got lost ... in a parking lot.
Cameras caught the fam -- and Brit's new friend (assistant?) -- getting confused in a back alley parking lot, as Spears almost hit yet another parked car while she weaved through paparazzi. Spears then drove onto a one-way street and blocked traffic.
Last Friday, Britney was charged with Brit and run and driving without a valid driver's license -- and it's still unclear whether Brit is legally OK to drive.
