Ethan Hawke and girlfriend 'expecting baby'

Training Day star Ethan Hawke is set to become a Dad for the third time.

The 37-year-old actor and girlfriend Ryan Shawhughes are expecting a baby - their first child as a couple.

Hawke already has two children, nine-year-old Maya and six-year-old Levon, with ex-wife Uma Thurman.

Hawke, who rose to fame in 1985 movie Dead Poets' Society, married Thurman in May 1998, but the couple separated and divorced five years later.

The actor met Shawhughes, 28, during his marriage when she worked as a nanny for the family.

"They are over the moon," a friend of the couple told In Touch magazine of the pregnancy news.

A rep for Hawke had no comment.
