Demi Lovato will feature on Nick Jonas' new solo album.

The Jonas Brothers star will release his self-titled effort on November 10 and he told On Air With Ryan Seacrest that long-time friend Lovato will cameo.

The two singers have teamed up for the song 'Avalanche' and Jonas told Seacrest on Monday (September 8):

"I did a duet with Demi, a song called 'Avalanche', which I’m really excited for the world to hear. I’ve got a song called 'Numb' that I wrote with Mike Posner, who’s an unbelievably talented writer and Angel Haze is featured on that. She’s incredible.

"And then it’s just a collection of songs that really sort of introduce where I’m at in my life right now as an artist and a person. I feel like it’s the best music I’ve made."

Lovato meanwhile took to Twitter on Monday to say: "So proud of you @nickjonas.. The world's about to see the talent I've witnessed in you since we were 14. You deserve it!!

"What I meant to say is you guys haven't seen @nickjonas's full potential. Get ready bitches."

Jonas acted as Lovato's creative director on her 2014 Neon Lights North America tour.

They previously worked together on the 2008 Disney movie Camp Rock.
