The two hit their first red carpet together earlier tonight at the Hollywood premiere of Moretz's new comedy Neighbors 2: Sorority Rising.
"Now, it's out. It's done," Moretz, 19, told me. "Get over it. It's real. We're together and that's it!"
Beckham, 17, actually surprised Moretz by flying in for the premiere from London.
"He's very sweet," Moretz said, adding, "He's a very very genuine man. He's a gentle man."
