Only Ariana Grande can make heartbreak look good. Last night, Ari -- along with Miss Piggy, Barbra Streisand and the Rockettes -- recorded their performances for "Michael Bublé's Christmas in New York," and the singer took on Wham!'s "Last Christmas."

In a tiny white shirt and matching top, Grande strutted up and down the stage singing, "Last Christmas, I gave you my heart/ The very next day, you gave it away." With snowflakes swirling, a big band played behind her as she ran up and down the notes of the song with plenty of Ari-esque ad-libs.
