The British supermodel threw a model-themed birthday party for friend Sadie Frost`s nine-year-old daughter Iris - her child with actor Jude Law - and taught the birthday girl and her own daughter Lila Grace, seven, her catwalk skills for a special show.

A source told Britain`s MailOnline website: "Kate had been teaching Iris and Lila Grace how to model and how to walk the catwalk properly in preparation for the party. They could hardly have a better teacher.

"All of the girls at the bash wanted to be Kate. She brought along lots of clothes for them and the girls had their hair and make-up done especially. She was teaching them how to master her famous hip swagger and her `I don`t care look` ".

The party went so well that Iris and Lila Grace now both want to be models like Kate.

The supermodel - who is currently dating The Kills guitarist Jamie Hince - also threw out all the stops for her daughter Lila`s seventh birthday in September where she spent weeks preparing for the karaoke bash.

A source said at the time: "Kate is pulling out all the stops to give her a really memorable day. It`s a karaoke party and Kate is really looking forward to belting a few numbers out."
