Melissa Rivers Fights With Boyfriend Over Missed Photoshoot On 'Joan & Melissa: Joan Knows Best?' (VIDEO)

Jason didn't think much of it when he opted to skip out on a photoshoot for "Hollywood's Happy Families" On "Joan & Melissa: Joan Knows Best?" (Tue., 9 p.m. EST on WE). He thought of it as just another photoshoot, but it meant something much more to Melissa. Joan Rivers suggested using a stand-in and Photoshopping Jason in later, but Melissa didn't like that idea. Jason thought it sounded fine, but for her it was the principal of the matter.

"We've talked about we're trying to have a baby," Melissa said to him. "We've talked about we're trying to do all these things, and then at the first opportunity you put work first."

"How about me make time away from cameras," he suggested. But things got ugly when he turned it around on her. "I can't be rational with you. You're so hormonal right now and irrational and I don't know why you're getting pissed."
