Bret Michaels Poisons Miley Cyrus

Miley Cyrus's follow-up to "Party in the USA" is a little less innocent than her hit. She's singing backup on a song that's part of Bret Michaels' solo album, Custom Built, "Nothing to Lose." But the lyrics of the song might mean she has a lot to lose, as in her reputation. The 46-year-old and 17-year-old harmonize on lyrics such as, "We both know better than this/Still we can't resist/Slowly get undressed." In the sensual chorus, they sing together: "Won't you fall down on me/So close I can feel you breathe." But the Poison frontman doesn't think it's such a big deal. "As God is my witness, there is nothing I have to be defensive about. I'm a good Dad. I just thought it was a beautiful song...Her first concert ever was Poison. Now I take my kids and they go see her play. It's awesome!" Originally, the Rock of Love star was set to produce Miley's cover of Poison's "Every Rose Has Its Thorn." But he played the new song for Miley at the studio during a break, and she wanted in on it. No word on what the video is going to look like...
