the Mystery Fart
BREAKING WIND NEWS -- Nancy Grace claims she's been FRAMED in the "Dancing with the Stars" fart mystery ... and tells TMZ an "investigation" is underway to find out who REALLY dealt it.
Grace -- who was doing a post-dance interview on the show last night when someone let it rip -- tells us, "As an ear witness on the scene, I can absolutely exonerate Tristan, myself and Brooke."
She adds, "However, the rest of the cast -- seated just inches away -- all remain under grave suspicion. The investigation continues."
