Eric Dane, Rebecca Gayheart, Kari Ann Peniche Sex Tape Leaked!

A sex tape featuring Eric Dane (Grey's Anatomy's "Dr. McSteamy"), his wife Rebecca Gayheart and former Miss Teen USA Kari Ann Peniche has just found its way onto the web.

The video was filmed at the 25-year-old ex-beauty queen's apartment. In the 12-minute-long clip, they appear inebriated as they take a bath in a jacuzzi tub and lay around naked in bed while discussing their porn names.

"My alter-ego name is Peter," Dane, 36, said, adding, "my dog growing up was called Cocaine, and I lived on Manor Drive, so I'm Cocaine Manor."

At one point, Gayheart, 38, says she has to lie down because she's "so high."

The tape reportedly surfaced as part of an official investigation into Peniche's alleged sex-for-hire business.

This isn't the first time Rebecca has found herself caught up in a scandal. In June, the National Enquirer published a photo of Rebecca back in 2003 high and naked in a bathtub with another woman.

Rebecca is known for being "the Noxema girl" and playing an ill-fated love interest for Dylan McKay on the original Beverly Hills, 90210.

Beauty-queen-turned-Hollywood-madam Peniche was crowned Miss Teen USA in 2002, but was stripped of her crown for posing in Playboy.
