Britney goes to the zoo
Britney Spears took time out of her busy party schedule to spend time on her 25th birthday with her 14-month-old son Sean Preston.
There is still no sign of 2 1/2-month-old Jayden James. From the looks of all the late-night partying the former Mrs. Federline has been doing, she has not seen much of little Jayden either.
