Former pro wrestler Hulk Hogan is suing a disc jockey, the DJ's ex-wife and a gossip website after a sex tape involving Hogan and the woman was posted online.
Hogan said in two lawsuits that he had consensual sex with his best friend's wife, Heather Clem, about six years ago in the Clems' home, but he did not know he was being secretly recorded.
"Mr Hogan had a reasonable expectation of his privacy, just as all Americans have a reasonable expectation of their privacy in their bedrooms," lawyer Charles Harder said on Monday.
The video was posted on the online gossip site Gawker. Hogan is seeking $US100 million ($A97.97 million) in damages from the New York-based media company, which declined to comment.
It's unclear who gave the video to Gawker.
In the suit against the Clams, Hogan claimed the video caused "severe and irreparable injury which cannot be adequately compensated by monetary damages." Hogan is seeking the rights to the video in both lawsuits.
Hogan, whose real name is Terry Bollea, wore a tight black T-shirt, black pants and dark sunglasses as he stood outside of the federal court in Tampa while his lawyers spoke to the media. He did not comment.
It's not clear whether Hogan and Bubba the Love Sponge Clem are still friends. The Clems have since divorced.
Hogan acknowledged on various TV talk shows recently that he had sex with Heather Clem while he was married to Linda Hogan. The Hogans have also divorced.
Hogan, his ex-wife and the couple's son and daughter have appeared on the reality show Hogan Knows Best.
Stephen Diaco, a lawyer for Clem, said Hogan was the best man at the Clem wedding and he is also a godfather to Clem's child.
"My hope is that these two can preserve their friendship," said Diaco.
