Julia Roberts was so scared of returning to big screen acting, that she decided toe ease herself in by doing voice over work.

The Oscar winning actress took a break from Hollywood after giving birth to her twins, Hazel and Phineaus.

Roberts� voice is currently featured in new animated film �The Ant Bully� as �Hova� a nurse who acts as a mentor to a young boy.

Roberts said of her career break: "Well, I did give birth to two children, so I didn't feel that to birth them and then abandon them was a wise mothering tactic!"

"I was out of work and out of shape. I had just given birth and decided a little dark room with a microphone was a good place for me to be!"

Expect to see Roberts back on the big screen soon�
