Jessica Simpson is dating Billy Corgan. See the...

Talk about an odd couple: pop singer Jessica Simpson and Billy Corgan of the Smashing Pumpkins are rumored to be dating.

The bald rocker isn't anywhere near as attractive as Jessica's ex's, including John Mayer, Tony Romo, and Nick Lachey. But according to an E! Online source, "She has fallen hard and is smitten," over Billy Corgan.

Isn't he too old for her? Billy Corgan is 42 and Jessica Simpson is 29. What do these two have in common? With Jessica Simpson's track record, should we just go ahead and add him to the list of her past relationships now?

Check out this picture of Jessica Simpson and Billy Corgan in New York City.

What do you think? Happy couple?
