LOS ANGELES — Billy Corgan is shedding new light on his relationship with Jessica Simpson, although he wants to refrain from putting a label on their rumored romance.

"If I go, 'Oh, we're just friends,' then it's like, 'Did they go out, did he dump her or she dump him, what happened?' " the rocker explains in the latest issue of Rolling Stone. "It has nothing to do with any of that. Sometimes people just like being around each other, and good things come out of that."

Corgan, 42, and Simpson, 29, first became the subject of dating rumors in December when they were photographed together in New York City. The unlikely pair grew close when they collaborated on the theme song for Simpson's new VH1 reality show, The Price of Beauty.
