APPARENTLY TILA TEQUILA HAD A MELTDOWN LIVE ON USTREAM! SHE GOT NAKED & STARTED WIGGING OUT!

QUOTE: I was watching Tila Tequila on Ustream! In the video the girl stripped totally naked... had a tampon string hanging... ranting about everything! This girl is so crazy!

Tila Tequila's lawyer blames his client's meltdown on former BF Shawne Merriman.

Attorney Cyrus Nownejad tells TMZ he thinks the "domestic violence" incident with Shawne in September may have "pushed her over the edge."

Nownejad acknowledges something is seriously wrong with Tila and he's trying to figure out how to get her some help.

Tila just took down her Ustream, showing her dancing nude and talking crazy in front of the camera. She also went off on Shawne and his alleged drug use.

Tila is suing Shawne for $1.5 mil over the September incident..
