Riding high off the success of their track "Tonight Tonight," Nashville's Hot Chelle Rae are prepping the release of their album Whatever, due out November 29.

In addition to the top 40 hit, HCR also show off their skills on 10 tracks, and they invited some pals to the party. Among those friends is Demi Lovato, who appears on "Why Don't You Love Me." The group's lead singer, Ryan Keith Follese, dished about the Unbroken singer to MTV News when we caught up with them at Sunday's American Music Awards (the group took home the prize for New Artist of the Year).

"Honestly, I'm really, really proud of the song we did with Demi," Follese said. "We did a song called 'Why Don't You Love Me' ... and we're such a huge fan of hers."

Lovato's big voice made her the perfect choice for the track. "She's such a powerhouse female vocalist for our generation and the one below us," he gushed, "And I just can't wait for the world to hear that song. She took it up a notch in a way that we couldn't have imagined."

So what should fans expect from the track? "It is such a ballad, such a duet. If you can imagine a classic love song, that's what it is," he teased.

Whatever features Lovato, but also appearances from the New Boyz on "I Like It Like That." Bei Maejor, who dropped the track "Trouble" with J. Cole earlier this year, appears on the song "Radio."
