Ariana Grande was a bag of nerves before her performance at the American Music Awards on Sunday night.
The 20-year-old singer - who is dating The Wanted's Nathan Sykes - announced to her 11 million-plus Twitter followers that she was struggling to keep her emotions in check before she took to the stage at the Nokia Theater in Los Angeles to perform her single 'Tattooed Heart' at the star-studded event.

"That was the most nerve wracking thing ever and I haven't had access to my phone all day but hi y'allllll love u I'm so nervous! u watching? (sic)"
The Nickelodeon star - whose debut album 'Yours Truly' has topped the charts in over 30 countries since it's September release - also picked up the gong for New Artist of the Year and after making a dutiful acceptance speech on stage, she quickly returned to the social networking site to thank her fans.
