Ethan Hawke and his pregnant girlfriend, Ryan Shawhughes, walk their dog in the West Village of New York City on Saturday.
As reported in January, Ethan, 37, and Ryan, 29, first met when she worked as the nanny during his marriage to Uma Thurman. Ethan and Uma divorced in 2003 after five years of marriage and two kids - Maya, 9 1/2, and Levon, 6.
"There's defininitely tension there," one insider told OK! about the former couple. "They try to keep it private for the sake of the kids, but now he's having a baby with a former nanny."
