Is Carly Rae Jepsen crushing on Taylor Swift's ex?

Carly Rae Jepsen has plenty of superstar fans, including Justin Bieber, Selena Gomez, and Miley Cyrus, but it was a special gift she received from John Mayer that made her giddy. "He sent a note in a little wooden box that said, 'Embrace and enjoy your first hit. There's more to come.' [Opening it], I was acting like a 12 years old," Carly says. "He's a great songwriter- and not bad to look at!" Carly has mentioned that everyone deserves to meet their heroes and admits that John is one of hers. But maybe she should take a word of advice from Taylor's song, "Dear John" that says, "I'll look back and regret how I ignored when they said run as fast as you can." Proceed with caution, Carly!
