Watch Ariana Grande Perform 'Needy' for iHeartRadio Music Awards

Multiple stars hit the stage at last night's iHeartRadio Music Awards including Alicia Keys, Halsey, Cardi B, and even Guardians of the Galaxy star Chris Pratt.

One of the top performances from the night actually came from an artist who couldn't make it to the award show in Los Angeles. Ariana Grande pre-recorded a performance of her hit song "Needy" from her recently released album, Thank U, Next.

Eyes were glued to the TV screen not only because this was Ariana's first performance of "Needy," but also because the new look the star sported during it.

Ditching her usual peplum dress and thigh-high boots look, the Grammy award-winner donned a different, but equally gorgeous, look.

Not only did Ari perform, but she also won three iHeartRadio awards, including Pop Album of the Year and Artist of the Year.

Other artists who took home awards included Drake, Taylor Swift, Bruno Mars and 5 Seconds of Summer.
