Inside Jessica Simpson & Billy Corgan’s Budding Romance

Jessica Simpson, 29, is dating Smashing Pumpkins singer-songwriter Billy Corgan, 42. But the question remains: What do they see in each other? “Since things got serious in November (after flirting at a party in L.A.), she’s telling her friends that she wants to have his children,”.

“Not right this second, but eventually,” explains the insider. “She’s fallen for his personality, charm and mellow, artistic style.”

As for Billy, “he’s very caught up in Jessica’s mystique and believes this is a relationship worth pursuing.”

But Billy wants to take things slowly, adds the source. “He’s a brilliant man but a hard guy to constantly be around. It’s going to be very interesting to see how much of his personality and attitude she might take on.”
