Angelina Jolie says her three-month-old twins are "very smiley".

The actress has revealed Knox Leon and Vivienne Marcheline are a joy to be around because they are already developing distinct personalities.

She said: "They're great. They're still so little, but they do have their own personalities. They are starting to get very smiley, and they are at those months where their personalities really start to shine."

The 33-year-old star added her other children - adopted trio Maddox, seven, Pax, four, Zahara, three, and two-year-old Shiloh, the twins' natural sister - are starting to become interested in her work, and are particular fans of her role as Tigress in 'Kung Fu Panda'.

She said: "I think it's a great film, and it's brought a lot of joy to children - and to my children, absolutely. My kids do love it. They are very, very proud. They have mom dolls everywhere. They have the Tigress. They love Tigress. They have a big Tigress doll that they keep putting diapers on! They love Tigress!"

It was recently revealed Angelina's children convinced her to play video games as a way of losing her post-pregnancy weight.

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.

"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!"
