An insider tells E! News that Callahan "had a girlfriend that worked on the show at the time. They were together, and he cheated on her with [Papa]."

The 28-year-old Papa -- who was booted from the show Monday -- maintains that she did not have a sexual relationship with Callahan. She says they were just friends, but Bachelor producers made up the fling to drive ratings.

"There was no making out!" she said this week in a radio interview. "Unfortunately, I did not get any out of this big sex scandal that supposedly happened. If I had known that I was going to get accused of it, maybe I would have gone for it!"
