Steven Tyler performed with Motley Crue frontman Vince Neil over the weekend in South Florida - but the biggest fireworks weren't coming from the stage.

The Miami Herald reported a CATFIGHT between Tyler's girlfriend, Erin Brady, and a hot young thang who had her eye on the scarf-lovin rocker.

Sorry to report. There are no pictures...yet. We're still looking, though and will update this page as soon as one of the trashy sites posts any!

All of this supposedly took place in the VIP section (where else?) of Pangaea following Friday night's (Dec. 7) ninth annual Fort Lauderdale Harley-Davidson Bikers Bash.

One report:

"A woman from the tribe was trying to take a picture of Steven Tyler," said one witness. "At the same time, Steven's girlfriend was coming back, I think from the restroom. Apparently, Erin got in the way of the picture or something, and some words were exchanged."

"Next thing everyone knows, the two girls are going at it," the witness said. "Scratching, hair-pulling, hitting. It lasted about six seconds, then security broke it up . . . Steven got up to try to pull them apart, but it happened so fast, he really didn't have time to do anything. Security was right on top of it."

"Tyler and security broke them up and everyone had a good time till 5:30 a.m.," said Pangaea co-owner John Surgent.

The event raised money for the Boys & Girls Clubs of Broward County. Tyler said he got involved in the fundraiser through his friends Bruce Rossmeyer, owner of Fort Lauderdale Harley-Davidson, and Plantation's Richie Supa, the acclaimed Aerosmith songwriter best known for the hit "Amazing".

"There is only one way to beat addiction: you have to hit bottom," Tyler said. "You have to have some DWIs, get arrested, be humiliated, have your wife and children leave you, have your friends and band members walk away. Addiction is a one-way street to death, jail or insanity."
