John Mayer creates guitar for Katy Perry for Christmas

Los Angeles: Musician John Mayer has designed a guitar for singer Katy Perry to gift her on Christmas.

The couple have been dating for the past five months. The 35-year-old musician had the guitar covered in intricate designs, including Katy`s initials and the date they first met.

"John has put some serious effort into his Christmas gift for Katy," quoted a source as saying.

"Since they met he has been trying to prove he isn`t the guy everyone says he is. This should definitely prove that - every little detail on the guitar shows how much he thinks of her," the source added.
