Emma Watson, best known as Hermione from the Harry Potter films, is reportedly dating tech entrepreneur William "Mack" Knight. Since he's not an actor or another type of Hollywood bigwig, relatively little is known about Knight. But that doesn't stop relentless fans and journalists from digging deep and trying to learn more about him.

According to People, Watson and Knight were first publicly spotted together after seeing Hamilton on Broadway in New York. They also may have vacationed together recently in Big Sur.
