Simpson wasn’t such a fan of Lachey when Jessica married the former boy-bander in 2002. “Everybody thought, including my father, that my marriage to Nick would kill my career,” Jessica told in 2004, a year before she and Lachey separated.
But Joe Simpson says Mayer is a different story. “I think the beautiful thing is that [he and Jessica] don’t do the same thing,” he told. “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.”
