Why didn't Billy Corgan ever come clean about romancing Jessica Simpson?

"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?' It has nothing to do with any of that," he tells Rolling Stone. "Sometimes people just like being around each other, and good things come out of that."

The Smashing Pumpkins frontman, 42, says his goal in life is "to love whoever I think is worth loving, and I think if people knew her like I knew her, they would love her like I do. It's really simple."

Corgan and Simpson, 29, grew close when he helped her pen part of the theme song to her VH1 reality show, The Price of Beauty.

Simpson even shared photos of a recording studio collaboration with the rocker - via Twitter. "I am blessed," she wrote, adding that it was "fun to be lost in laughter."
