Former professional wrestler Hulk Hogan is suing a disc jockey, the DJ's ex-wife and a gossip website after a sex tape involving Hulk and the woman was posted online.
Hulk 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.
The video was posted on the online gossip site Gawker. Hulk is seeking 100 million US dollars in damages from the New York-based media company, which declined comment.
It is unclear who gave the video to Gawker.
In the suit against the Clems', Hulk claimed the video caused "severe and irreparable injury which cannot be adequately compensated by monetary damages". He is seeking the rights to the video in both lawsuits.
Hulk, whose real name is Terry Bollea, wore a tight black T-shirt, black trousers and dark sunglasses as he stood outside the federal court in Tampa while his lawyers spoke to the media. He did not comment.
It is not clear whether Hulk 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 while he was married to Linda Hogan. The Hogans have also divorced.
Stephen Diaco, a lawyer on the Clem side, said Hulk was the best man at the Clems' wedding and he is also a godfather to their child.
"My hope is that these two can preserve their friendship," he said. "I can't comment on the suit. This has caused harm to Bubba and he didn't release it, he didn't condone the release of it. He wants to find out who did that and he wants that person to be held accountable."
