Some “Anatomy” has hit the Net — and it ain’t “Grey’s.” Eric Dane, best known for his role as “Dr. McSteamy” on ABC’s Grey’s Anatomy, and his wife, ’90s-era Noxzema Girl Rebecca Gayheart, are featured in a new sex tape, filmed with former Miss Teen USA 2002 Kari Ann Peniche-turned-Celebrity Rehab contestant sometime after the couple’s wedding in 2004.

On Monday, Gawker posted excerpts from a tape that appears to feature the stars and the former beauty nude in a bedroom and a bathroom.

In the 12-minute-clip, all three appear to be intoxicated as they take a bath in a jacuzzi tub and lay around naked in bed discussing their porn names. “I need to lay down too,” Gayheart can be heard saying from behind the camera at one point. “I’m very high.”

We’re not sure what’s more frightening; the fact that celebs still haven’t figured out how to keep their naughty bits off the Interwebs or that The National Enquirer has been uncharacteristically accurate as of late.
