Though the idea of Britney Spears and Ellen DeGeneres caroling together may sound cute in concept, it's hard to believe Spears would perform even "Frosty the Snowman" sans lip-synching or Autotune.

Sure enough, on today's edition of DeGeneres's show, the two did more dancing than singing, and they did it to the pleasing holiday notes of "Womanizer" (a contemporary redo, we believe, of the seasonal classic "I Saw Mommy Kissing Santa Claus"). While DeGeneres got into the spirit and her neighbor appeared to find the tableau strangely erotic, Spears herself was subdued enough to lure producers into complacency, finally bolting for the nearest bus before her father (wielding a taser and a skillet of cheese grits) tackled her, dragging her back to the porch stoop, then to Robertson to close out his bill at Kitson.
