The X Factor and former America's Best Dance Crew host married fiancee Courtney Mazza in an outdoor ceremony in Punta Mita, Mexico on Saturday, People reported.
According to People, the sunset wedding took place at the seaside estate of Girls Gone Wild creator Joe Francis and was followed by a reception which featured a mariachi band and a wedding cake created by Cake Boss star Buddy Valastro.
Viewers will get a chance to see the event on Mario & Courtney's Wedding Fiesta, a two-hour special which will air on TLC on Saturday, December 8.
Lopez, 39, and Mazza, 29, met in 2008 when he starred in Broadway's A Chorus Line musical, where she was a dancer.
The couple are the parents of a two-year-old daughter named Gia -- whose birth served as the basis of Mario Lopez: Saved By the Baby, a reality series which aired on VH1 in 2010 and followed Lopez and Mazza as they prepared for the birth of their first child.
Lopez and Mazza got engaged in January. The wedding is reportedly the first marriage for Mazza and the second for Lopez, who married actress Ali Landry in a 2004 ceremony which was later annulled.
