VIDEO: '13's Ariana Grande Performs on TODAY

Ariana Grande appeared on this morning's TODAY show on NBC to talk about her debut album "Yours Truly" which dropped today. The album has already hit No. 1 in the U.S. The singer also treated fans to a performance of two tracks off the LP, 'The Way' and 'Tattooed Heart.' Check out the appearance below!

"I was hoping that it would do well, but I didn't expect it to go to No. 1 so quickly!" the 20-year-old petite singer with the big voice told Savannah Guthrie and Willie Geist.

GRANDE, who starred in the original cast of Broadway's '13', teamed up with a diverse bevy of friends for her debut album. Big Sean delivers a magnetic verse on the shimmering "Right There", which fans receive as an instant download with their pre-order of Yours Truly and is already #4 on the iTunes Pop Chart. She also trades irresistible harmonies with The Wanted's Nathan Sykes on her ballad, "Almost Is Never Enough"-also available on the soundtrack for one of the summer's hottest films, Mortal Instruments: City of Bones. In addition, the album includes an unshakable rendition of the Broadway classic, "Popular Song," with multi-platinum international star Mika.

For YOURS TRULY, GRANDE hit the studio with a variety of in-demand writers and producers including the legendary Babyface as well as Harmony [Beyoncé, Kelly Rowland, Fantasia]. As a result, the entire tracklisting is a dynamic and diverse affair.

GRANDE rose to immense popularity starring as the beloved Cat Valentine, culminating in her own hit series Sam & Cat. The series premiered on Nickelodeon in June 2013 and is now a bona fide hit for the network. Singing and performing since the age of eight, music remains GRANDE's first love.
