Angelina Jolie has been using her children's video games to lose weight.

The 33-year-old actress - who raises six kids with partner Brad Pitt - has been burning off her post-pregnancy pounds with a Nintendo Wii console, which requires players to use their body to control their games' characters.

A source said: "Angelina's kids were convincing her that video games were more than just fun. They explained to her you can do anything from practice math to learn to read music and exercise."

'Wanted' star Angelina - who gave birth to twins Knox Leon and Vivienne Marcheline in July - is said to be particularly taken with the 'Let's Pilates!' game.

The source added to America's OK! magazine: "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!"

It was recently revealed the actress had a "mommy tuck" following the birth of her twins, and didn't lose the weight through breastfeeding as she recently claimed.

A source close to Angelina said: "She doesn't like to talk about it or admit it, but Angelina told some friends that she had a 'mommy tuck'. She likes the way that sounds better than 'tummy tuck'."
