Perry sported a pair of ripped blue jeans and a tie-dye spaghetti trapped shirt for the outing. She finished her look with a pair of sunglasses and a white handbag. As for Mayer, he donned dark jeans and a stonewashed denim shirt over a white T-shirt. He accessorised the casual outfit with dark-rimmed glasses, a silver beaded necklace and a blue bandana on his head.

Perry, who divorced from Russell Brand back in 2012, started dating Mayer following the divorce. Although Perry and Mayer allegedly split earlier this year, the pair was spotted in late April spending time together at Disneyland in Anaheim, California.
