    According to the actor, the photo was taken at the 2016 MTV Movie Awards — and he was inspired to drop trou by, of all people, Zac Efron.

    "The year before, Zac Efron had taken his shirt off on stage, and he is so sexy," Alexander said.

    So when it came time to present an award with Samuel L. Jackson — his costar in that year's The Legend of Tarzan — Alexander decided to one-up Zac and get down to his skivvies.

    "I decided to also show a little bit of skin," he explained. "I couldn't take my shirt off because Zac had already done that, so I thought, 'Well, then I'll take my pants off, because it's equally sexy.'"

    Just for reference, here's Zac taking his shirt off at the 2014 MTV Movie Awards.

    The question remains: Was Alexander's moment equally sexy? Well, you can be the judge of that.
