LOS ANGELES -- "Grey's Anatomy" star Eric Dane and his wife, Rebecca Gayheart, are suing a celebrity gossip Web site over the release of a video showing the couple hanging out in the buff with a former beauty queen.

The video -- shot two years ago -- shows Dane, his wife, actress Rebecca Gayheart, and Kari Ann Peniche -- a dethroned Miss United States Teen -- "wacked out" and in the buff, according to published reports.

The lawsuit for copywright infringement was filed Wednesday in U.S. District Court in Los Angeles. The suit contends that Gawker.com leaked four minutes of the video showing Gayheart, 38, and Dane, 36, sharing bed, bath and beyond with Peniche under the headline, "Dane's Anatomy."

The lawsuit seeks $1 million in damages and an injunction preventing any further distribution of the video online.

Gawker publisher Nick Denton posted the following response on Twitter: "To quote the great Marty Singer -- Eric Dane's lawyer -- `If you don't want a sex tape on the Internet, don't make one!"'

Gayheart had a recurring role on TV's "Beverly Hills 90210" in the mid-1990s, and has more recently guest-starred on "Ugly Betty."

Dane plays "McSteamy" Dr. Mark Sloan on ABC's "Grey's Anatomy."

Peniche, 25, was named Miss Teen United States in 2002 but was stripped of the title after appearing nude in Playboy.
