As it turns out, his name is Roberto Aguire, and while he's not all that new or mysterious, he is an interesting and handsome fella!
Roberto, 27, met Emma, 25, while filming Harry Potter and the Goblet of Fire. "I was doing an internship in the special effects department at the time," he recalled to JustJaredJr.com back in 2012, "and one day we had a chance encounter that lead to us spending half a day together exchanging stories and dance moves. We never really lost touch after that and now she's one of my best friends."
