Britney is chilling outside, smoking a cigarette and wearing a denim mini-skirt with her buttcheeks hanging out. Smoking gives Britney gas, so she blasts a big fart fart! She keeps on smoking anyway, and the camera zooms up from underneath as she blasts a huge stinky fart through her pink panties! She's not done, though, since she has a tummy ache from eating too much. Britney just keeps farting and farting - who knew so much gas could come out of such a cute little lady? What a fantastic clip!
