Britney Spears was back from her big hearted business trip to NYC and quick to reunite with Jayden James and Sean Preston in LA this weekend. On Friday she picked up the boys from school with her dad Jamie and on Saturday night the foursome were spotted on their way to dinner at the Mondrian hotel. On Sunday, she headed to the go-kart track in Anaheim for some fun, all documented by the camera crew she brought with her. This week is a big one for Britney's "Womanizer" — it hits iTunes on Tuesday and the video is set to debut on the October 10 episode of 20/20. There was a mini preview during last night's Desperate Housewives, looks like it's going to be hot. While it has a spot on my workout mix already, I have a feeling we'll be hearing this one all over. Who knows, maybe even SP and JJ like to show off their moves to mom's new hit.
