Jillian for President! TigerGate 2009 continues to dominate watercooler gossip as one of the week’s hot topics, but who would have expected Jillian Michaels — the tough-as-nails fitness trainer from NBC’s Biggest Loser — to weigh in on the brewing scandal?

While the rest of the world is still in awe over the seemingly straight-laced sportsman’s mass philandering, Jillian was hardly surprised –she had Woods pegged as a horse’s ass years ago.

“He put the moves on a very good friend of mine,” says Jillian, who first heard about the golfer’s sex scandal while cruising the trending topics section on Twitter. Though she didn’t specify exactly when Tiger tried to pounce on her pal.

“I knew he was an ass**** ages ago, I did,” the health guru chuckled at the Biggest Loser season-eight finale in Los Angeles on Tuesday night. “Sorry. I didn’t need to watch the news to find that out.”
