Jamie Lynn On All Fours -- Yama-Hee-Ha!
Lil' pregnant Jamie Lynn Spears had a play date with her high-powered big wheel -- an ATV -- on Wednesday.
While sitting on her four-wheeler, the 205-month old munched on what appears to be either a popsicle or some sort of meat on a stick.
Hopefully she wasn't riding around in the ATV, because JL wasn't wearing a helmet or a seatbelt. What does this chick have against playing safe?!
