Actor Ethan Hawke and his girlfriend/former nanny, Ryan Shawhughes are expecting a baby together.

"I can confirm and they are thrilled," says Hawke's rep Mara Buxbaum. "No further details will be made available."

Hawke has two children from his six year marriage to actress Uma Thurman: daughter Maya Ray and son Levon Roan.

I wonder why so many men hook up with their children's caregivers: is it a primitive instinct that makes someone who cares for your offspring highly attractive or just because you are around each other so much?
