While we don’t know anyone who could argue with dance-happy Ellen Degeneres, a new report has American Idol judges Simon Cowell and Ellen’s working relationship starting off on the wrong foot.

“Their relationship started poorly but now the situation has escalated,” a source told Radar Online.

It was reported that Simon arrived an hour and a half later for Idol’s first taping with Ellen (which has not aired yet), upsetting the talk show host.

But a source who was at the taping says Simon was late, but not that late. “He showed up exactly 14 minutes late,” said one person who was there.

However, the show started taping without the British music mogul. “People were surprised the show started without Simon,” said one observer.

Onlookers say the tension between Simon and Ellen escalated, alleging that when the cameras stopped recording they didn’t speak to each other.

“There’s two camps on the show this season,” said an Idol insider. “It’s a lot more tense than previous seasons. It seems as if Ellen has decided to try to take control since Simon is on his way out and that’s created problems.”
