Yes it is, in fact, possible that Killmonger could be your boyfriend, because he just admitted to Ellen and Chrissy that he does hookup with fans. Or at least that he has before.
In shock that a man as beautiful (and talented and smart and stuff) as Michael B. Jordan is single, Ellen tried to get the tea on his dating life. It wasn't until Chrissy explicitly asked "Have you ever hooked up via direct message?" that MBJ admitted to doing something other than filming or working out.
"I have, I'm human, I'm human," he said, shyly. "Not often, but yes, I have."
