Lopez proposed to Mazza while the couple was vacationing in Mexico. Extra cameras, of course, taped the big moment. "I've come to the realization that I'm never going to meet another woman as special and amazing as the one I have and I think she's finally succumb to my pressure and will take me," Lopez told the camera before proposing. "So we'll see, I hope."
Lopez and Mazza welcomed a daughter, Gia, in September 2010, a journey which was documented on the VH1 reality show, Mario Lopez: Saved By the Baby. They have been together since 2008.
Lopez wed model Ali Larter in April 2004, but the marriage was annulled two weeks later.
Extra will air the proposal on Wednesday's show. Watch a preview here:
