Ethan Hawke, who has called fatherhood “the greatest pleasure in my life,” and his wife, Ryan Hawke, welcomed their second child together two weeks ago, a girl named Indiana, PEOPLE has confirmed.
She’s the fourth child for Hawke, who also has two kids with ex-wife Uma Thurman. News of this pregnancy was first reported in April.
On Friday, the family had lunch at La Bottega in the Maritime Hotel, in Manhattan. “He was very happy,” an onlooker tells PEOPLE. “Seemed like a proud daddy.”
