John Mayer has won over Joe Simpson.  Although he didn’t have a lot to live up to, being that Papa Joe didn’t really like Jess’ ex-husband, Nick Lachey.  “Everybody thought, including my father, that my marriage to Nick would kill my career,” Jessica told 20/20 in 2004, a year before she and Lachey separated.

So it’s green lights all the way for Jessica and John.  “If Jessica is in love, I love the things she is in love with,” Joe Simpson, 49, told People magazine of Mayer at the Entertainment Weekly upfront party at The Box in New York City on Tuesday.

There’s even a bit of professional admiration going on with Papa Joe.  “I want her to be happy. I’m always a fan of his. I love him; he’s got great music.” Indeed, Mayer is becoming something of an anomaly of pop and classic rock.

“I think the beautiful thing is that (he and Jessica) don’t do the same thing,” he told People magazine. “He’s a legend already. There is no competition. He’s a guitarist; that’s his thing. Jessica is a singer. She doesn’t play guitar, so there’s no competition.”

It looks like Jessica has finally found someone that she can bring home to daddy.
