Uh-oh! It looks like we might have to update our list of the best holiday songs ever. Jessie star Debby Ryan just posted an amazing cover of the classic holiday song "Santa Baby" that we're totally obsessed with — and so did Ariana Grande, with some help from her former Victorious co-star Liz Gillies!
We think both versions of the tune are totally fantastic, but we want to know which one is your favorite: Debby's more rock 'n roll take on the holiday hit or Ariana and Liz's playful duet. Listen to them both, and then tell us which star you think nailed it in the comments!
