Natalie is already a mum to five-year-old son Aleph with husband Benjamin Millepied, whom she married in 2012.
The working mum recently penned a piece for the New York Times describing her life as an actress and mother.
“When I’m not working, I’m pretty much exclusively with my family, so my rituals have to do with school, meal preparation, playdates, bedtime,” she wrote.
“[Parenthood] made me much calmer under stress, because there’s that weirdparent thing you develop, that when things get really bad, your voice gets calm and your blood pressure slows, and you can make everything okay again.”
Natalie was also joined at the premiere by her co-star, Lily-Rose Depp.
