Who DO you LOVE?? John Mayer is inviting fans to enter his #BKLovesMayer Flyaway Contest, a social media photo competition inspired by Who You Love. That's the current single, featuring girlfriend Katy Perry, from his sixth studio album, Paradise Valley.

He and Billboard launched the contest via Mayer's Instagram account (@johnmayer) and are encouraging fans to share stories of who or what they love by posting an Instagram image with the hashtag #BKLovesMayer.

The winner gets a trip to meet Mayer and attend his show at the Barclays Center in Brooklyn on Dec. 17.

The contest, in support of his partnership with Citi for his 2013 fall tour, runs through Nov. 26, and Mayer will choose the winning Instagram photo in early December.

In a separate sweepstakes, five fans have a chance to win signed copies of Mayer's album by visiting billboard.com/bklovesmayer.
