Former 'Biggest Loser' star calls Andy Cohen 'not a nice dude'

Jillian Michaels is calling out Andy Cohen.

The former "Biggest Loser" trainer appeared on the "Skimm'd From the Couch" podcast recently, where she opened up about her apparent feud with the "Watch What Happens Live" host.

"Andy Cohen, I mean, is just not a nice guy," she said on the podcast, per Page Six.

Their tiff started after Michaels criticized the popular keto diet, which led to Cohen naming the celebrity trainer as his "jackhole" on an episode of "WWHL."

"I had a really crappy experience with him on his show," she continued. "And I've said, like, this is not a nice dude. I think I'm one of the only people that said, 'Your behavior is unacceptable.'"

"He's like constantly looking for ... a way to pick at me," she added.

Michaels considers Cohen, who famously helped create Bravo's "Real Housewives" franchises, someone who also does not support women.

"Really, you've got a guy that just likes to attack women," she went on. "He doesn't believe in keto. He's just an a--hole."
