On Thursday, the twosome celebrated Valentine's Day with a romantic dinner date in Los Angeles.
Perry, 28, stunned in a floor-length white-and-red dress. Mayer, 35, looked a bit more casual in slacks and a denim coat, but he threw on a festive red-and-blue scarf for good measure. Adorably, the duo held hands as they exited the restaurant.
But Mayer is not the only love in his gal pal's life.
Looks like Perry had a happy Thursday, too!
