Angelina Jolie has confessed that when she and Brad Pitt started seeing each other, she wasn't so sure it would work out.

The Changeling star wasn't convinced that her actor boyfriend would warm to her children but super dad Brad rose to the challenge.

Angelina tells OK!, "At first I was worried.

"But when I saw how much he enjoyed being with the children – teaching them things and being such a great father – I just knew it would work between us.

"What makes me happiest is watching him play with our kids.

"As a mother, you feel so reassured to see your partner sharing your commitment to your children as well as being there whenever you need him to take over when you’re feeling exhausted!"
