Relationship details: Katy and John began their on-and-off-again relationship last Summer. After splitting briefly in late August, the duo quickly reconciled and amped up the seriousness. Katy and John spent Christmas with her family, attended the presidential inauguration together, and showed front-row affection at the 2013 Grammys. They abruptly called it quits in March but were rumored to be rekindling the romance after spending Memorial Day weekend together with friends. This past week, the pair both proved that they are going strong since he dedicated a love song to Katy on the opening night of his Born and Raised World Tour in Milwaukee, WI, and she shared a picture of the duo cuddling on the Fourth of July.
