Upon hearing the news of who his fake wife was, Santoro was thrilled: “That was the best!” the Brazilian actor said at the Los Angeles premiere. “I loved the story line. Then I said, ‘Who’s going to play the wife? Really? Let’s do it!” And the American Idol judge didn’t disappoint. “She was incredible,” he added. “She was so sweet and so down-to-earth. It was so easy and we just had so much fun with it.” Now that’s a cute on-screen couple! Catch the pair in the movie, along with Elizabeth Banks, Cameron Diaz, and more, in theaters now.
