Source: Bang ShowbizHulk Hogan's sex tape has "embarrassed" his family.The 'TNA IMPACT' star was stunned earlier this month when intimate footage of himself and Heather Clem appeared online, and though his ex-wife Linda Hogan is "devastated" by the clip - which was filmed while they were still married - she wasn't shocked by the film.Linda - who has children Brooke, 24, and Nick, 22, with the wrestler - said: "It really is quite an embarrassment for our family. I'm a little devastated, but I'm not really shocked."I knew that he was having affairs and I knew that he was cheating."Although Linda claims Hulk - whose real name is Terry Bollea - had affairs during their marriage, she insists she didn't know he had slept with Heather, who is the estranged wife of his best friend Bubba the Love Sponge.She told 'Access Hollywood': "I didn't know about this girl."Linda says she wanted to watch the tape to find out if she knew the woman in the video and to see whether it took place during their marriage.She admitted: "[Watching it] actually did make me upset."I mean, to watch him in a room with another woman... and at the end of the day he came out and said it was definitely during the time [we were] married."
