There's no doubt that Ariana Grande is talented and beautiful, with a few big hits under her belt already, but is the 21-year-old destined for a career that can rival Mariah Carey's? A$AP Ferg, for one, definitely thinks so.

The Harlem rapper, who released his debut album Trap Lord last year, is featured on Ariana's upcoming second LP, My Everything, on the song “Hands On Me," and he has big predictions for her future.

"She's the next Mariah Carey. She's dope," Ferg told MTV News on the BET Awards red carpet last weekend. "And that's not an understatement, or an overstatement -- I just see her as that next big voice that's gonna pop."

In regards to their collaboration on "Hands On Me," he would only say that "it's a dope song," and he can't wait for us to hear it.

We haven't heard Ferg on many pop collaborations yet, he says that it's all coming together organically.

"It's not really strange because I do a lot of festivals, like Coachella, Bonnaroo [and] people don't see what happens behind stage," he explained. "I'm a rapper, but Fergie from the Black Eyed Peas comes to my trailer, I'm hanging out with Selena Gomez... and all of these people that love my music."

"So it's just about that time we put the art together."

Last week Ariana Grande brought back MTV's "TRL" for a day as "Total Ariana Live," and one of our favorite moments was her Broadway-inspired rendition of A$AP Rocky's "F---in' Problems."
