Mario Lopez and Courtney Mazza's wedding taped to air on TLC Dec. 8

"The X Factor" co-host Mario Lopez and his girlfriend of four years, Broadway dancer Courtney Mazza, are now a married couple. The pair got hitched Dec. 1 in Mexico and the big event was taped for the TLC special "Mario and Courtney's Wedding Fiesta," airing Dec. 8.

Lopez and Mazza's 2-year-old daughter Gia was the flower girl. "The only thing that's going to change is my last name," Mazza tells Us Weekly. "Same love, same everything!"

Lopez and Mazza also got engaged in Mexico on New Year's Eve 2011. They originally met while working on the Broadway revival of "A Chorus Line."

We hope Lopez listened to the advice he got from "X Factor" pal Khloe Kardashian.
