Naughty or nice? MTV will take viewers inside a yuletide celebration at a familiar Beverly Hills residence with "The Osbourne Family Christmas Special," airing Dec. 11 on the cable network, Billboard reports.

Word from MTV is that the program promises to take "holiday specials to a bizarre new level," as the cast of guest stars and their performances would certainly attest.

For starters, Jessica Simpson and Ozzy will deliver a "Winter Wonderland," while newlyweds Dave Navarro and Carmen Electra will bake cookies.

"Loveline" host Adam Carolla will join Jack Osbourne to prepare cranberry sauce as Kelly Osbourne croons "Have Yourself a Merry Little Christmas."

Billboard says the showstopper will likely be the group reading of "'Twas the Night Before Christmas" featuring an all-star cast of matriarch Sharon Osbourne, Outkast's Big Boi, 'N Sync's JC Chasez, Eddie Griffin, Tracy Morgan, Anthony Anderson, Eva Mendes and Electra. Caroling to follow.

Meanwhile, on a less Christmas-y note, Sharon Osbourne, 51, spoke to TV's "Extra" Thursday night, to address her recent confession that she cheated on Ozzy with the late Randy Rhodes, the legendary lead guitarist for Ozzy's solo band.

"Before my husband and I actually were engaged, before we were married, I had a great friendship, as did my husband, with Randy," said Osbourne, who admits to the brief fling with Rhodes in the Osbournes' new memoir, "Ordinary People."

Osbourne tells "Extra," however, that the fling was not extramarital. "I definitely wasn't married to my husband at the time. Randy died before my husband and I were married," she said.
