Jessica Simpson

Jessica Simpson

Billy Corgan has fuelled rumours he is romancing Jessica Simpson - after refusing to confirm or deny if he is dating the pop singer.

The odd couple is rumoured to have begun dating in December after the stars were snapped together during a night out. Sources claimed the longtime pals had taken their relationship to the next level and were "officially dating".

But Corgan, 42, has refused to go public about the alleged romance - deflecting questions about the status of their relationship. When asked if he was dating "Jessica", Corgan responded, "Jessica Rabbit? She's a cartoon character. I don't know if you knew that. They did such a good job on the movie that you swore she was real."

Simpson, who has also yet to publicly acknowledge she is dating the musician, recently revealed the pair has teamed up for a new song. She has been single since splitting from American footballer Tony Romo last summer.
