Emma Roberts worked double duty on the set of new romantic comedy Valentine's Day - the young actress turned babysitter for her aunt and co-star Julia Roberts in between her own scenes in the film.
The Roberts are among a host of Hollywood actors starring in the film, including Jennifer Garner, Jessica Alba, Jessica Biel and Bradley Cooper.
But instead of hanging out with the star-studded cast when she wasn't needed for filming, Emma found herself looking after her little cousins - five-year-old twins Hazel and Phinnaeus, and Henry, two.
Emma tells Us Weekly magazine, "I didn't have scenes with her, so I babysat the kids while she was on set.
"She really is just a mum, at the end of the day. She's totally normal, which I love."
The ensemble cast movie has captured the hearts of film lovers in the U.S. as it topped the box office this weekend.
She returns to the big screen later this year with 4.3.2.1 ... The Countdown Begins, which will also star and will be directed by Noel Clarke.
