Hello, Butt Cheeks! Mario Lopez Trims His Tree Wearing Barely There Briefs [Photo]

Mario Lopez trims his tree, sans pants.

Holy backside, Batman Slater! Now, we've seen Mario Lopez donning a wrestler's singlet during his past stint on "Saved By The Bell," but this is a whole different story. Hey, we'll take it!

Christmas came early this year when a cheeky candid of Lopez sporting some red-hot briefs popped up on Twitter. (Is it too late to amend our "Hottest Milfs and Dilfs of 2012" list?) The sexy photo--guest-starring 2-year-old daughter Gia--was posted by the dimpled star's wife, Courtney Mazza. She bragged, "My husband looks hot rockin his @RatedMOfficial with his little elf....#lovethem," and we can't say we disagree with her! Turns out the revealing skivvies are from Mario's own line of underthings, Rated-M Official. And while they're clearly the perfect outfit for tree decorating, the pantless celeb sadly does not come included in the package.

Lopez's 2-year-old daughter, Gia, covers up more for the occasion.
