WATCH: Ariana Grande’s Medley Performance at the 2014 American Music Awards

Ariana Grande, accompanied by The Weeknd, gave a beautiful performance at the 2014 American Music Awards tonight. She performed a medley of her songs – “Break Free,” “Problem”, and “Love Me Harder.” Grande was wearing a black, sheer, lace mermaid gown with black undergarments and her hair was half up, half down. Her soft and sultry performance was stunning, as was her dress.

Check out some of the below Vines from the performance, including one of Grande’s brother Frankie.

A really adorable moment was watching her brother Frankie jumping up and down in excitement in the crowd. Check it out in the below Vine.
