Real World Ex-Plosion heats up once again as Brian confesses to Jenny that he made a huge mistake.

Jay G Talks 'Fun and Games' With Ex, Jenna

Now that Brian has arrived in the house, he and Jenny have rekindled their romance. While they're out to dinner, Brian reveals to a confessional camera that it's the "perfect" time for him to admit that he kissed another girl, because she can't throw anything at him or make a scene.

"The other night, for me, I don't know if I was necessarily 100% on point with you know, all the expectations we have. You know, talking about in our relationship."

When Jenny asked him to clarify he added, "I don't know. There were girls all over the place. People were getting numbers. I may have gotten a number. I may have danced with a girl or something like that, I don't know."

She then told him he pretty much needs to say exactly what happened, because she is going to see it when the episode airs anyway. He bit back and said he'll also see everything that happened between him and Cory, another housemate that Jenny was hooking up with before Brian arrived. When she asked him if he acted out of "resentment" with another girl he said no.

"It's just stupidity is what it is...I remember flirting with this one girl in particular and then at the end of the night I got her number or something like that. I was dancing with her and I kissed that girl that nigh too."

Jenny then broke up with him and said they no longer need to be together.

She then said in the confessional she doesn't like how he told her.

"I'm about ready to slap him. We are in a public restaurant. Smart move Brian."
