The businessman was working with Vergara's boyfriend Nick Loeb when he and the Modern Family star split, and he gave his pal some sage advice after overhearing one phone call between the pair.
Guest hosting news show Access Hollywood Live on Thursday morning (19Jul12), Deutsch recalled, ""He was actually at my house and he was talking to her on the phone and I was a man behind the scenes... Truth be told, we were talking about kids and they were talking about whether to have kids or not and I said, 'You've gotta say that that's a price of entry, that's a deal breaker; you want kids... and I don't care how much you're in love with her, if you want kids and she doesn't, that's a deal breaker.'
""Obviously that was something that went into the deal and it sounds like it's good.""
Loeb and Vergara reconciled shortly afterwards and the businessman proposed to the lovely Latina during her 40th birthday celebrations in Mexico earlier this month (Jul12).
