Linda Hogan was sickened by Hulk Hogan's sex tape.

The 53-year-old former reality TV star - who split from the retired wrestler in 2007 after 24 years of marriage - admits she wasn't shocked that her ex-husband cheated on her with her friend Heather Clem but was disgusted that she only found out about it from the leaked recording.

"I knew something was going on behind my back, I just didn't know it was so close to home. I was at her wedding! That tape was sickening. Watching them do that behind my back turned my stomach," she said.

The mother-of-two - who shares daughter Brooke, 24, and son Nick, 22, with her 59-year-old ex - says the affair which happened shortly before their split clarified a lot of issues in their marriage: "He couldn't even look me in the eye sometimes during our relationship, and I bet he thought I was too busy to notice his lies."
