Jennifer was last spotted out with her daughters just last week as she took them to a library.

Earlier this month the couple revealed they had decided to let their daughters choose the name of their unborn child.

'Our girls are working on names. At first they were definitely Disney. It was like, Donald Duck, Minnie Mouse Affleck. And then they’ve moved on. Then it was Peter Pan, Captain Hook, Smee.

'They’re coming up with lists and coming in and saying, ‘Let’s have a baby-naming contest! Let’s have a baby-naming poll! They ask everyone, because they just want to know. But we’re not telling,' she told E! Online.

Jennifer will also play a mother in her new film, The Odd Life of Timothy Green, which will be released August 15.

In
it, she and co-star Joel Edgerton play a 'childless couple who bury a
box in their backyard, containing all of their wishes for an infant.
Soon, a child is born, though he is not all that he appears.'
