Kristen Doute and James Kennedy broke up during last night's Vanderpump Rules, and after the episode aired, Doute spoke out about her former boyfriend's infidelity.

Understandably, Doute was incredibly shocked as she watched last night's new episode play out.

"Watching the episode back I felt naive and betrayed," Doute told Bravo TV on Monday. "To hear him compliment Jenna at the after party the way that he did, as I sat there, and then brag about 'boning' her while I stupidly took him back was beyond humiliating."

"At the time, I didn't really have a reason not to believe James and DAMN his story was convincing," Doute explained. "There was a slight doubt in my mind, but I blamed myself for that because of the mistakes I had made (and lies I had told) in past relationships. James did his homework and knew exactly how to play me."

During the show, Kennedy lied to Doute before admitting his mistake to Bravo cameras.

"I promise you I didn't have sex with her," Kennedy told Doute during a scene from last night's show. "I've never had sex with anybody but you in the whole relationship. I still want you to be my girlfriend."

However, during his confessional, Kennedy said, "At this point I'm just lying to Kristen for her own good because I know if I tell her the entire truth it's just going to devastate her. The truth is, Jenna and I were definitely boning."
