The relatives - made up of Kris Jenner, Bruce Jenner, Kim Kardashian, Khloe Kardashian, Kourtney Kardashian and Rob Kardashian, as well as husbands, partners and younger siblings - have solidified a deal with the E! network for more instalments of the series, which is the biggest deal ever in reality TV, according to TMZ.com.

The seventh season of 'Keeping Up with the Kardashians' is due to begin on May 20.

The deal reportedly does not include all of the associated products and brands which come with the family.

Kim, Khloe and Kourtney - who began appearing on E! in 2007 - are believed to be making some shows in the UK this summer.

A source said: "The family really feel that they've conquered reality TV in America with a number of different shows and spin offs, so the UK is the next country they want to break.

"The Kardashians love England and think they could get up to a lot of fun - and trouble - with a summer in London. It would make great TV as well as boosting their profile internationally."
