Mariah Carey has announced two bizarre musical collaborations for the near future.

The singer will feature on Bone Thugs-N-Harmony's comeback album, due out this year, as well as working with country legend Willie Nelson.

"I am so influenced by their style that it kind of merges together" Carey said, talking of the Bone track she features on. "It's funny, because so many artists today are influenced by Bone, and they may not even realize it."

The collaboration with Nelson comes as part of Carey's new film, Tennessee. Mariah plays an upcoming singer/songwriter, and reveals that she has co-written one of her character's songs with Nelson himself.
