Back in January, Jessica Simpson and Billy Corgan were photographed making sweet music together in the studio. Relationship rumors exploded once Simpson tweeted, "I am blessed," she told her Twitter followers. "Going over a song w@billy and the boxer." But now Corgan is opening up about their relationship ... working relationship that is.

"She asked me to help her out on the theme song for her new TV show [VH1's 'The Price of Beauty']," the Smashing Pumpkins frontman, 42, tells the Chicago Tribune. "[The show] has an interesting concept. She goes around the world to show how different people perceive beauty. In some cultures, bigger is better. In some, smaller is better. It's interesting."
