A first glimpse: Sean Federline's forehead
For all we know, this could be a baby doll. Someone on a messageboard I post on suggested she take a doll outside and start throwing it in the air to give the paparazzi a heart attack. Note that these photos are different than the ones that came out this morning showing her and her mother holding her dog. Lynne Spears looks to be holding Sean in these photos, while Britney holds her dog.
