Chris Harrison Speaks Out on Bachelor Scandal

The Bachelor host Chris Harrison has confirmed rumors that a bachelorette had an affair with a show producer during filming.

Will it be the most dramatic Bachelor season ... ever?

"It was embarrassing for us ... incredibly unfortunate, [and] horrible decisions were made," Harrison told a Los Angeles radio station Monday, the day of The Bachelor season premiere on ABC.

The producer has been fired and the contestant was kicked off the show, Harrison added.

"This was the rare time that before I had to go talk to the girl, Jake and then the women, I had lawyers, psychologists, producers, executives saying, 'Okay, these are the words you can say,'" he said. "It was intense. It was a wild night."

It's unclear how many rose ceremonies the bachelorette in question made it though in her quest for Bachelor Jake Pavelka's affections.
