Ariana Grande's AMAs Performance Earns Her Standing Ovation From Lady Gaga

Ariana Grande's performance of "Tattooed Heart" at the 2013 American Music Awards on Sunday night managed to shock the likes of Lady Gaga, who gave the young songstress a standing ovation.

Grande performed the single off her album, "Yours Truly," leading with an a cappella rendition of "The Way," on the AMAs stage at the Nokia Theatre L.A. Live on Nov. 24. She sang her heart out in a performance MTV News has compared to the Motown vibe of Gladys Knight and the Pips, in front of an audience packed with music greats like Gaga, Justin Timberlake and Taylor Swift.

The 20-year-old was one of the most talked about acts of the night, E! News noted, and the performance earned her applause from the "Do What U Want" signer, as well as Ciara.

She also took home the New Artist of the Year Award.

"Oh my God! I'm so nervous," she said when she took to the stage to accept the honor. "Thank you so much. This is for my fans. I have the most loving and supportive fans in the world, and I love them so much. I'm so nervous ... This is crazy. I love you. Thank you."

She then turned to Twitter to reach out.

Not only has her singing career taken off, but Grande recently celebrated the premiere of her new Nickelodeon show, "Sam & Cat." The show is a cross-over spin-off starring Grande, who played Cat Valentine on "Victorious," and Jennette McCurdy, who played Sam Puckett on "iCarly," Entertainment Weekly noted.

CORRECTION: A previous version mistakenly reported Grande sang an a cappella version of "Baby I." She actually sang "The Way." This error has been fixed.
