This is what dreams are made of.
The two sat down for a new episode of Billboard's Quizzed series, during which Duff tested Trainor's knowledge on facts about the 2003 movie, including where Lizzie and Gordo (Adam Lamberg) shared their first kiss, how Paolo (Yani Gellman) whisked her away and what Ethan Craft's (Clayton Snyder) favorite food was.
Trainor flawlessly answered questions about the movie -- which Duff recently watched for the first time since its premiere. "I actually watched it over the weekend with my son because I hadn’t seen it since the premiere," she said. "There was a very big portion of my life that I was like, 'I’m good for a minute.' … [My son] was in and out, but my future husband … he loved it the most. I was like, 'You're such a nerd!'"
Trainor couldn't have been more starstruck by Duff, until Snyder walked in with a plate of spaghetti. "Wow, you’re so handsome still. You guys aged so well!" the pop star screamed. "I’m sweating so bad! You look like Hercules!"
Duff will reprise her role as Lizzie in Disney+'s upcoming reboot. See what she told ET about the series in the video below.
