More evidence that Chris Brown's latest accuser is full of it -- TMZ has video footage showing her walking on the leg she claims Brown seriously injured ... minutes after the alleged incident.

The video was shot early Sunday morning in the Heat Ultra Lounge parking structure in Anaheim, where Deanna Gines was being escorted out by security.  She's clearly upset, telling the bodyguards, "F*** all y'all!"

As we reported, Gines claims Chris Brown shoved her to the ground inside the club, tearing the ligaments in her right knee.

But the video appears to contradict her story ... because you see Gines putting weight on her right leg and limping on her left.

Sources at the club tell us, Gines did actually injure herself ... but it was her own fault, drunkenly stumbling down some stairs on the way out of the club. As we reported, the club's owner (as well as several eyewitnesses) claim Chris never touched Gines.

For Gines' part, she tells us she did NOT fall outside the club -- the club's trying to cover its ass. As for the mystery limp, she says her whole lower body was in pain after Chris allegedly shoved her ... and at the time, her left leg hurt more than her right. Oh yeah, and she was drunk.
