The 23-year-old's character Draco Malfoy is seen with kids at the end of the new movie, Harry Potter and the Deathly Hallows: Part 2, in an epilogue scene with his real-life girlfriend, Jade, making a cameo playing his wife.
According to PEOPLE, he said: 'It was a lot of fun to play onscreen hubby and wife for a bit and have a kid for three days. Three days is a good amount of time, for anyone wondering.'
Speaking about kids in real life, he said: 'I'm talking decades away. But, yeah, thank you for the prompt.'
