Jessica Simpson's dating history has included a host of pop singers — from ex-husband Nick Lachey to John Mayer. But recently, she's been linked with a different kind of musician – grunge era kingpin Billy Corgan.
"She has fallen hard and is smitten," a source told the Web site.
While a rep for Corgan had "no comment" when contacted by Access Hollywood, the source told E! the two think of themselves as "officially dating."
Billy, 42, who previously has been linked romantically with Courtney Love and Tila Tequila, may reportedly be making Jessica happy, but another source told E! he hasn't fit in with the family yet.
"He's just another in an endless string of Jessica's boyfriends," the source said. "They think he's too old for her. No one takes any of her boyfriends seriously anymore because she has had so many. They're sick of all of them being 'the one.' "
