John Mayer surprised a fan by purchasing her dream guitar for her.
The 'Free Fallin'' singer and girlfriend Katy Perry popped into a guitar shop in Soho, New York, last Friday and after spotting 16-year-old Julie Fermin admiring the expensive instrument John decided to buy it for her.
John asked the teen - who has been playing guitar since she was 11 - which instrument she liked best and then took it to the till.
She told Us Weekly magazine: "We started freaking out and getting super excited."
She added: "I showed him, and he went over and checked the guitar's price, I said, 'Yup, but I can't afford it,' and he said, 'Oh, stop it!"
Both stars posed for pictures with the fan -which she later posted on Twitter - and said their goodbyes, when an employee revealed to the fan John had bought the guitar as a gift for her.
She gushed: "I was so shocked, I started crying and screaming. I cannot describe all the emotions I felt at that moment. I just knew I was the luckiest and happiest person alive."
The lucky fan took to Twitter to share her excitement.
She wrote: "I never in my life thought I'd meet and get to talk to Katy Perry and John Mayer, I literally thought it was impossible.FOREVER MIND BLOWN. (sic)"
