Corgan: 'Simpson rumours like a cartoon'

Billy Corgan has clarified his relationship with Jessica Simpson.

The former Smashing Pumpkins frontman, who has been romantically linked to Simpson, has insisted that his relationship with the pop singer is strictly platonic and professional.

Speaking to the Chicago Tribune, Corgan said: "Simpson asked me to help her out on the theme song for her new TV show."

When asked about what he thought of the romance rumours circulating about the pair, he added: "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."
