Poison is on a pre-planned break this year, but frontman Bret Michaels isn't having trouble finding other folks to work with -- including Miley Cyrus and his fellow cast members on the new season of "Celebrity Apprentice."

Michaels and Cyrus have traded guest appearances for each other's next albums; she sings on his new single "Nothing to Lose," while Michaels guests on a cover of the hit Poison ballad "Every Rose Has Its Thorn" that's slated for Cyrus' next album.

"Miley got ahold of me and wanted to re-cut 'Every Rose...,' " Michaels tells Billboard.com. "When we were in the studio, I said, 'Do you want to hear some of my new tracks?' She said 'I'd love to,' and I played her 'Nothing to Lose' and she fell in love with it and said she'd love to sing on the song. I was like, 'That'd be killer!'"
