Ariana Grande and Elizabeth Gillies Cover “The Christmas Song” (Video)

Ariana Grande gives a smile as she leaves her handprints in cement at Planet Hollywood in NYC on December 22.

Ariana stopped by Planet Hollywood to promote her new single “Put Your Hearts Up.” If you haven’t picked the song up yet, get it on iTunes.

Ariana also has another special song to share. She recently teamed up with her “Victorious” costar Liz Gillies for a cover of “The Christmas Song (Chestnuts Roasting On An Open Fire).” They have such beautiful voices! Ariana writes, “This is something Liz & I threw together late one night two weeks ago after work as a “Happy Holidays” from the two of us.. Enjoy the silliness and singing.. We love you! Xoxoxo”
