is hosting an 'X Factor' birthday bash for her daughter Lila Grace's ninth birthday next week.
In a bid to make the party as authentic as possible, the 37-year-old supermodel has enlisted the help of pals Sadie Frost
and Meg Matthews to make up a judging panel that will rate the singing talents of the youngster and her friends.
A source told The Sun newspaper: "Lila is a massive 'X Factor' fan and so is Kate. It's become a Saturday night tradition, sitting together and rating each act.
"Kate came up with the idea of having an 'X Factor'-themed party and wants to make it as realistic as possible."
Kate - who is married to The Kills
rocker Jamie Hince - and her mates are also planning to dress up like past and present judges from the UK version of the show - which include Simon Cowell, Cheryl Cole, Gary Barlow, Sharon Osbourne
and Tulisa Contostavlos.
Parents will also be allowed to perform and guests will be allowed to show off other talents other than singing.
