Hollywood’s most notorious playboys, Mario Lopez and Joe Francis, have tamed their wild ways. The two were spotted having a low-key dinner at XIV Restaurant in LA with their girlfriends. Francis is celebrating his “union” with TV reporter Christina McLarty in Mexico on Nov. 6, while Mario and Courtney Mazza will have their first child in one month. A spy said, “They were overheard talking about how excited they were for the new baby and how their kids would be best friends.”
