Anna Kendrick hated pregnancy talk on What To Expect set

Actress Anna Kendrick was left feeling queasy on the set of What To Expect When You're Expecting when the creator of the story dished out intimate details about pregnancy.

The new parenthood movie is based on a best-selling guide by Heidi Murkoff and the writer looked on as some scenes of the new film were shot.

But Kendrick was far from comfortable with the topic of conversation when the cameras stopped rolling.

Speaking on BBC Breakfast, she says, "Heidi who wrote the book was there sometimes. You can't really have a conversation with her without finding out something you just didn't want to know about pregnancy.

"Some people are fine with that and I find myself going a little green when I hear about some of the things."
