Angelina Jolie has her children to thank for her post pregnancy figure, after they reportedly introduced her to Nintendo.

The mum-of-six is said to have stumbled across a game called Let's Pilates! which has helped her to lose the baby weight in just a couple of months.

"The kids were convincing her that video games were more than just fun," a source tells OK!.

"They explained to her you can do anything from practice math to learn to read music and exercise.

"She tries to get in an hour of Pilates three times a week. She's picking it up pretty quickly and is already at the hardest setting!"
