Dean McDermott may be packing on the pounds, but judging from his cozy lunch with his ex wife, Mary Jo Eustace, last week -- she doesn't care! On Feb. 9, the former flames were spotted having a very intimate lunch together in Los Angeles, which has sparked cheating rumors, reports In Touch.

Days after news broke of the potential affair, the father of five was looking rather displeased following a business meeting on Thursday morning. We couldn't help but notice how Dean's tight t-shirt hugs his protruding belly in an unflattering fashion. We'd be depressed too if we looked like that in a shirt!

We can't imagine that Tori Spelling is happy about hearing that her cheating hubby met up with his ex wife -- especially when the reports are claiming that the duo looked quite chummy. “Mary Jo and Dean were so at ease with each other, they looked like a married couple,” a witness at Le Pain Quotidien in Studio City told the mag. “They embraced the moment they saw each other, talked for almost two hours and then warmly hugged each other when they said goodbye.”

We hope Tori has a tracking device on that dude. He can't be trusted!
