Lopez proposed to Mazza last New Year's while the couple was vacationing in Mexico, which was later aired on Extra. Lopez, 39, and Mazza, 31, 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.
Considering most of their relationship has been televised, it should come as no surprise that their nuptials will be too. TLC will air a two-hour special of their big day on Saturday, Dec. 8.
Lopez's married X Factor co-host Khloe Kardashian offered up some advice for his wedding day: Leave your hosting skills at home. "You and your partner should take a few minutes to yourselves and just watch the whole thing from the audience," Kardashian told People. "[My husband] Lamar and I will now talk about those little moments, because you get pulled away from each other. You shouldn't spend your whole wedding not with each other."
Lopez had wed once before. In April 2004, he tied the knot with Ali Landry in Mexico, but she had the marriage annulled less than two weeks later over his alleged infidelities.
