His father is one of the most respected actors of his generation, with an Oscar to his name and several successful films under his belt.
The blonde actor has worked with Gwyneth Paltrow and Angelina Jolie.
And there is a connection to Ben Affleck.
Her mother did not enter the Hollywood business as she was a single mother and working as a waitress when she met the megastar.
But she always looks great on a red carpet in designer dresses and high heels.
Together, this power couple raises four children: one is hers alone, whom she had before they met, but they had the other three together.
They were all spotted side by side at a movie premiere in New York City on Wednesday night.
