John Mayer spent his birthday with Katy Perry in New York where they were seen being rather flirty.
John is rocking an even shorter look than we saw him with over the weekend.
After spending the day together, they got a little more dressed up and took the birthday partying out for the night as well.
Katy & John it seems have taken their summer fling to the fall and it looks like it could be real as both singers have been quite mum about their relationship in the past couple of months.-DocFB
