Ariana Grande took to the stage at the A Very GRAMMY Christmas event in Los Angeles on Tuesday evening.
The Problem singer wore a frilly white outfit for her solo performance of Santa Tell Me.
The 21-year-old pop star was later joined on stage by her boyfriend Big Sean as they performed the track Best Mistake from the brunette beauty’s new album, My Everything.
The pair ended months of speculation when they finally confirmed their relationship last month.
Other performers at the hour-long entertainment special hosted by rapper LL Cool J included Mary J Blige, Pharrell Williams and Maroon 5.
A Very GRAMMY Christmas will air in the US on 5 December and feature performances of holiday songs and current pop hits, as well as artists sharing their favorite holiday memories.
