The 43-year-old actress has said that her first job ever was baby-sitting and tutoring so that mothering part in her was always in action, reported the New York Post online.
"I have always had a very strong mothering instinct. My first job ever was baby-sitting and tutoring... That mothering part of me has just always been in action," she said.
The 'Men In Black 2' star was in a relationship with Oscar-winning director Danny Boyle since 2012 before they broke-up last year.
She is currently filming 'Finally Famous'.
