Mayer strums star heartstrings

Though John Mayer, 30, has said he "just doesn't go for celebrities," the singer has been linked with quite a few women who are just that. As recently as this past weekend, Mayer was seen in Mexico with current flame Jennifer Aniston. What makes these ladies susceptible to Mayer's mystique?

"He's the classic deep and soulful musician," says Stacy Kaiser, a psychotherapist and relationship expert who appears on VH1's Celebrity Fit Club. What woman wouldn't want a song such as Your Body Is a Wonderland, one of Mayer's hit singles, written about her? Kaiser adds.

Furthermore, Mayer is an overall good guy, says Christie Nightingale, who runs Premiere Match, a high-end matchmaking company. "He seems to be in touch with his emotional side," Nightingale says. "Most girls swoon over that."
