Carly Rae Jepsen cherishes note from John Mayer

Singer John Mayer made pop sensation Carly Rae Jepsen's year when he sent her a hand-written note to congratulate her on hitting the top of the charts.

Justin Bieber's protege stormed onto the music scene earlier this year (12) with the release of her smash hit Call Me Maybe.

The track's popularity has continued to rise thanks to YouTube.com covers by superfans Katy Perry, Miley Cyrus, James Franco, and Bieber's girlfriend Selena Gomez, but the blushing 26 year old confesses it was a compliment from her former crush Mayer that she cherishes the most.

She tells People magazine, "John Mayer 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-year-old. He's a great songwriter - and not bad to look at!"
