It seems things are 'on again' between the continuous 'on and off' couple Katy Perry and John Mayer after the two were spotted together on December 31. According to reports, the two entered the same car after partying hard on the New Year's Eve. Perry sported a white, short sleeve, colourful maxi dress while Mayer wrapped himself up in a black wool coat. This on and off since 2012 couple last sparked speculations several months ago when they attended Girls stars Allison William's wedding.
