Another star Alexander had fun with is Rihanna, who he joins for several scenes in her feature film debut, “Battleship,” which hits theaters on May 18.

“She’s pretty amazing,” he said.

But the actor noted that he wasn’t surprised by how easily Rihanna took to acting.

“I was honestly not surprised. Just like, watching her on stage, or her videos, you can tell [from] her energy and her charisma and personality, you know that she’s gonna be great in that part,” he said. “I knew that and she really is.”

You know what this means? It means he totally got down to the Rude Boy video.
