Mariah Carey and Justin Bieber's new music video for "All I Want For Christmas Is You" had many critics deeming the stars' interaction as inappropriate, however Mimi's hubby says he "loved it."

Nick Cannon tells Life & Style:

    "It wasn't scandalous. I loved it, and I'm so proud of her."


In the holiday video, Bieber, 17, is seen ogling at Mariah, 41, who is posing in a sexy Santa costume. We'll admit, it's a bit awkward to watch, but Mariah's post-baby bod is looking fab!

As for Cannon leaving twins Moroccan and Monroe in care of Bieber, Cannon adds:

    "Oh hell no [would I ever let him baby-sit]! Justin didn't meet our kids because Mariah didn't bring them to the set of the video. But I think he will eventually.”


If Biebs babysat the twins, who would babysit Biebs?
