But Seal insists he put his own bad boy behavior behind him when he married Klum in 2005 and he would never risk embarking on an affair himself.
He tells Britain's Sunday Mirror, "It's really unfortunate what happened to Tiger and Elin. But I'll tell you how I feel about it. You're Tiger Woods, right? You're the first billionaire athlete, you very, very rarely, if at all, hear the word 'no'. It doesn't exist... I don't condone it but I get why he did it...
"I do understand why people are tempted and I understand why people do it. Have I cheated before? Hell, yes! Not in my marriage, but in relationships before. And it's not because I'm trying to be a good man or trying to resist temptation. I mean, I'm married to one of, if not the most wonderful woman in the world. She is everything - funny, attractive, hardworking, she has integrity, she loves me to bits.
"Honestly, if I was looking at myself and I cheated, then I'd just think, 'Wow, how disappointing, I actually thought you were better than that.'"
