Billy Corgan and Jessica Simpson: Just ‘Good Friends’

Billy Corgan and Jessica Simpson: Just ‘Good Friends’:According to People – When Jessica Simpson released photos of her laughter-filled recording sessions with former Smashing Pumpkins frontman Billy Corgan last month, buzz that the two are dating reached its highest volume yet.

At the time, a source told PEOPLE, “He got her number and starting calling her. He thought she was cute … adorable … and she got a little crush.”

Now Corgan himself has clarified the nature of their relationship – sort of. “[Simpson] asked me to help her out on the theme song for her new TV show,” he told the Chicago Tribune of the alterna-pop tune he composed for VH1’s The Price of Beauty, premiering Mar. 15.

As for the romance rumors, Corgan, 42, said, “The stuff that I’ve seen doesn’t have any bearing to the reality that I’m in. It’s like being in a cartoon. It has nothing to do with what’s really going on or how I feel.”

And despite the fact that Simpson’s current Allure cover story could be interpreted as evidence of her growing feelings for Corgan – “I definitely will marry an artistic man,” says Simpson, 29. “I don’t have a physical type. I have an emotional type. When you have yourself together, I don’t care what you look like at all” – a source close to Simpson tells PEOPLE the pair are “good friends.”
