The 19 year old, who starred in Valentine's Day alongside her famous aunt earlier this year (10), spent her childhood visiting the Pretty Woman actress on film sets.
And the experience gave the young star a taste for acting because she got to meet so many famous faces.
She says, "It's kind of cool to have been around it for so long, to see if I wanted to get into it. I would visit my aunt and you'd have to drag me off set. My mum would be like, 'Emma, it's midnight. You have to go to bed'... I was seven and in the background of one of the scenes (of Julia's 2001 movie America's Sweethearts), which was so much fun. It was just my aunt and me. We hung out a lot. I got to meet Catherine Zeta-Jones, which I thought was the coolest."
