Ethan Hawke a father of four, wife Ryan Shawhughes give birth to daughter Indiana

Ethan Hawke has been a new father for a few weeks now, and no one even knew.

US Weekly reports the "Gattaca" actor and wife Ryan Hawke (née Shawhughes) welcomed their second child together a few weeks ago, a daughter named Indiana.

The couple, who wed in 2008, were spotted walking with the newborn and big sister Clementine (3 years old) in New York on Aug. 5.

Hawke has two older children -- daughter Maya (13) and son Levon (9) -- with ex-wife Uma Thurman, who he divorced in 2004 after six years of marriage.

He and his second wife met when she briefly worked as a nanny for his and Thurman's children.
