MONTH 7: FEBRUARY

Following months of low-key dating, Mayer goes public about Perry on CBS Sunday Morning. "I don't feel like I'm in a celebrity relationship," he says, while also admitting he "was just a jerk" for his past foot-in-the-mouth antics (which notably preceded his 2009 breakup with Aniston). The duo cap off the month by attending the Grammys together. And just weeks before leading separate lives, Mayer presents Perry with a heart-shaped stunner for Valentine's Day. Perhaps his 2001 song "St. Patrick's Day" aptly sums up the couple's romance: "And we'll both be safe 'til St. Patrick's Day."
