"There was a lot of kissing going on in that preview, huh?" Hough shot back, referring to the clip from her film that just aired.
"No, it's not that. It's a question I've been meaning to ask you and I don't want you to feel uncomfortable," her boyfriend said before slowly reaching into his suit jacket pocket to pull out a…piece of note paper. (Hough's initial reaction: "Oh, God!")
Rather than present her with a diamond engagement ring, the Idol host asked that she do him a favor. "Will you...give this note I wrote to [Rock of Ages costar] Tom Cruise? I'm such a big fan -- I loved him in Cocktail," Seacrest told Hough.
Ever the good sport, Hough relaxed and bantered right back with her boyfriend.
"Wait, but didn't we write that [note] together last night?!" she said.
