Mirror Mirror star Lily Collins had a taste of childbirth during her latest movie Love, Rosie and was so thrilled by the experience of playing a young mother she insisted on keeping her prosthetic belly.
The actress daughter of Genesis star Phil Collins ages a decade in the film and she had to take labour lessons from a real midwife.
She tells Lucky magazine, "She explained how I should scream and push - it was so exciting."
Collins has a weird keepsake from the set: "I creepily kept my stomach and have it at home now, because they were going to throw it away."
However, the role didn't inspire her to start a family right away: "One day I would love to be a mom, but right now I'm so excited about my work."
