Britney: I am Not an Animal!

Britney Spears turned into an unwilling zoo critter on her birthday.

While most people took pics of zebras and chimpanzees at Los Angeles Zoo on Saturday, paparazzi snapped pix of Brit and son Sean Preston. Spears celebrated her 25th birthday with her adorable son and friends, checking out the baboon habitat.

Spears and clan then hopped into a mini-tram as paparazzi chased after them like a pack of flashing gazelles.
