Hulk Hogan claims a intimacy tape allegedly featuring him and a mystery brunette was "secretly filmed".
The legendary wrestler is furious about the recording – which is currently being offered for sale to porn companies – and has branded it an "outrageous invasion of privacy".
According to TMZ.com, the footage shows the 58-year-old WWE champion – real name Terry Bollea – getting intimate with an unidentified brown-haired woman who is not thought to be his blonde wife Jennifer McDaniel or ex-wife Linda Hogan.
However, it is not know when the tape was made.
"We will take all necessary steps to enforce both civil and criminal liability."
Hulk Hogan has already taken legal action against ex-wife Linda – who he was married to for 23 years before their 2009 split – over allegations she lied and defamed him in her book ‘Wrestling the Hulk – My Life Against the Ropes’.
In it she claimed her husband had physically abused her and had a transgender relationship with another wrestler.
She wrote: "Hulk tore my shirt, threw lamps, and held me down on the bed with his hands around my throat during arguments.
"I was always afraid he would kill me in one of his rages."
In retaliation, Hulk filed an 18-page lawsuit in Florida last December.
