It's probably safe to say she won't be getting the First Impression Rose. Nick Viall hooked up with one of his contestants from the forthcoming season of The Bachelor long before the show was ever filmed, a source exclusively tells Us Weekly.

"During the first day of taping, all of the girls came out, and he actually had slept with one of them at a wedding and never called her again," the insider tells Us.

Neither of the onetime bedmates acknowledged their past sexual encounter after reuniting on set, the source adds.

A second insider says Viall told producers that he "didn't want any girls on the show that he already knew or had a date with" because he felt "it was a waste of a person being there."

Viall, 36, is certainly no stranger to drama on the hit ABC franchise. The Milwaukee native — who was announced, in a shocking twist, as the season 21 Bachelor in August — most recently butted heads with Josh Murray on season 3 of Bachelor in Paradise, where the Bachelor season 10 foes both vied for Amanda Stanton's heart. (Murray and Stanton are now engaged.)

The model was also the runner-up on season 10 of The Bachelorette, in which he lost Andi Dorfman's final rose to Murray, 32. A year later, he came in second once again (behind Shawn Booth) on Kaitlyn Bristowe's season of The Bachelorette.

Earlier this month, Viall was spotted filming a group date for his season of The Bachelor while at a Backstreet Boys concert in Los Angeles. As Us Weekly previously reported, he and his ladies took the stage during the show, dancing along to "Everybody (Backstreet's Back)" and "I Want It That Way."

"Nick is a great guy," BSB member A.J. McLean exclusively told Us at the time. "I felt really bad for the girls because we only gave them 30 minutes to learn that whole dance routine, and the fear of God came over all of those girls' faces. They were such, such, such troupers. I wish them all the best of luck, and I do hope Nick does finally find that special someone."

The Bachelor returns to ABC in January 2017.
