Ariana Grande is prepping to release her debut album, "Yours Truly," and according to Starmedia, the official tracklisting features some exciting collaborations, including Big Sean, Justin Bieber and Demi Lovato!

Fans of both stars have been eagerly anticipating a duet between the two ever since Lovato told reporters that she and Grande were planning on working together.

"We've already talked about it," Lovato said at the time. "I love her so much. She's so sweet and so talented."

The duet is called "Direct Contact," and will be featured as a bonus track on Grande's new album, following a collab with Justin Bieber called "Supervised."

Lovato is set to release a new song of her own, a soaring rock ballad called "Heart by Heart" that will be featured on the "Mortal Instruments: City Of Bones" soundtrack. Along with Grande, Lovato would love to collaborate with her idol Kelly Clarkson and Taylor Swift.

Even though Grande had some trouble deciding on album art for her cover after some backlash from fans and critics over the original image on Twitter, she's finally decided on a sexy new image in black-and-white for "Yours Truly," set to hit stores Sept. 3.
