You don't know who this is, do you? I could keep you guessing all night but I bore easily so instead I'll just tell you: It's Adam Levine, frontman for Maroon 5. Who have apparently had some hits but frankly, I don't care. I only chose this photo for the bare-chestedness.
And for the fact that he obviously had his chest-bird tatt done by the same bisexual who did Rihanna's chest-bird tatt.
And also for the fact that he occasionally enjoys taking off his clothing, running through buildings and sharing the ensuing visual via Instagram. (Click here if you don't believe me.)
Not that there's anything wrong with that. This other perfectly normal celebrity does it all the time and his career is doing just fine. I'm not here to judge, folks. I'm just the vessel.
