Britney Spears and Kevin Federline are back in their Malibu, Calif., home with their newborn son, Sean Preston Federline.

People magazine reports in its issue on newsstands Friday that Spears' delivery date was actually moved up a day to Sept. 14, after she started experiencing contractions.

A source told People the 6 pound, 11 ounce infant never left his mother's side during their stay in the VIP suite at Santa Monica UCLA Medical Center.
