The Spanish beauty gave birth to her daughter, Luna, three months ago with husband Javier Bardem and Cruz says family will always be a priority to her.
"I've always been a very family person, since I was a little girl, that's the way I was raised. So that will always be a priority. But I have to work, like everyone else, so I will find a way to balance," the actress said.
The mother of two wore a red Nina Ricci suit for the London premiere of the film, which also stars Bardem, Brad Pitt, Cameron Diaz and Michael Fassbender.
'The Counselor' is all set to release on October 25.
