The release of Demi Lovato's 'Unbroken' is less than a month away, and the singer told Ryan Seacrest that her record will include cameos from Dev and IYAZ.

Dev, the voice behind the Far East Movement hit 'Like a G6' and her own new single 'In the Dark,' will appear on 'Who's That Boy,' a song produced by OneRepublic frontman Ryan Tedder, while 'Pretty Girls' singer IYAZ joins Lovato on a song called 'You're My Only Shorty.'

“One of the best experiences I’ve had was definitely flying down to Miami to go work with Timbaland and Missy Elliott," Lovato told the radio host. "Missy Elliott got on one of the tracks, and it's called ‘All Night Long.‘ It was really fun!"

We know that 'Unbroken' will contain Demi's comeback ballad 'Skyscraper,' which she performed triumphantly at the VH1 Do Something Awards. She plans to return to the road and has already announced her first couple of concerts. Lovato has already shared the cover art for the album, which hits stores on Sept. 20.
