If this is how Mario Lopez celebrates the holidays, where's our invitation?!

The "Extra" and "X Factor" host was snapped putting the finishing touches on his Christmas tree ... in a pair of revealing underwear.

Mario's new wife Courtney Mazza posted the shot on her Twitter, which shows the couple's daughter Gia supporting her pantsless dad as he put the star on their tree.

"My husband looks hot rockin his @RatedMOfficial with his little elf...#lovethem," Courtney tweeted along with the pic.

Mario has never been shy about his body, especially when it comes to promoting his underwear line (check out the hot gallery above!), but does anyone else find this booty shot a little odd?

Or do you decorate for the in your undies too?

Either way, Happy Holidays from the Lopez clan!
