Josh Groban's theory on how John Mayer snags beautiful women

"John's got a swagger that I've noticed," Groban said. "He's got a ‘tude that I have to try and learn how to get. It's that 'I may talk to you, I may not talk to you,' kind of thing."

"It doesn't hurt to play the electric guitar."

Alicia Keys, a longtime Mayer pal, says. "I think what's sexy about John is his intelligence. He's very smart; he's not like an average kind of guy," she explained. "He's creative. He plays the guitar – there's a certain natural sensuality that comes from that. He's also a great, great guy."
