VIDEO: Ariana Grande Sings RENT and Gives Best Carolee Carmello Impression

In the midst of her Honeymoon Tour, Ariana Grande has been sticking to her classic pop hits. At least on stage. Off stage, her warm-ups have been getting a little more creative.

The Grammy nominee recently posted a video to YouTube in which she took fans through some of her between shows fun. The video begins with her singing "Take Me or Leave Me" from RENT, and later, she even channels her inner Carolee Carmello (Tony nominee, PARADE) to sing "The Winner Takes it All" from MAMMA MIA! Check out both performances below! Skip to 2:00 for the impressive Carmello impression.

Ariana Grande got her start playing Charlotte on Broadway in Jason Robert Brown's 13 THE MUSICAL in 2008. With two GRAMMY Award-nominations including Best Pop Vocal Album for My Everything and Best Pop Duo/Group Performance for "Bang Bang" with Jessie J andNicki Minaj, a coveted performance spot on the 57th Annual GRAMMY Awards, a Platinum-certified #1 album for My Everything, several chart-smashing singles, a Billboard Women In Music Award, an MTV Video Music Award and a recently announced high-profile recurring role in a new FOX television series, Ariana has become an unstoppable force in pop culture.

Grande initially landed at the top with her first full-length album for Republic Records, Yours Truly. It debuted at #1 on the Billboard Top 200, Billboard Digital Albums Chart and iTunes Overall Albums Chart. Moreover, it yielded the game-changing pop smash "The Way" featuring Mac Miller. One of 2013's defining songs, the single went double-platinum, hit the Top 10 of the Billboard Hot 100 and reached #1 on the iTunes Overall Top Songs Chart. In the aftermath, she was named "Best New Artist" at THE AMERICAN MUSIC AWARDS in 2013.
