New generation: Kim Kardashian's younger half-sisters Kylie and Kendall Jenner, pictured here last week, are being eyed up for their own reality TV show
Plans are being made for up to three spinoffs from the popular show that will feature the youngest daughters of the family, 14-year-old Kylie and 16-year-old Kendall.
The head of the cable channel E! has revealed she plans to add more Kardashians to the roster of TV shows featuring the family.
Bonnie Hammer said the network is looking at making shows featuring mum Kris Jenner's two daughters with husband Bruce.
Kylie and Kendall's half sisters are Kim, Kourtney and Khloe Kardashian.
The two youngest Kardashians feature in Keeping up with the Kardashians but have minor roles compared to the older sisters.
But, with Kris' carefull coaching, they are emerging as young starlets on the scene.
Kendall recently launched a modelling career while Kylie is dating Australian pop star Cody Simpson.
Rob Kardashian, who was a runner up in the Dancing with the Stars reality show, is also being looked at for a possible show.
Hammer, 61, told The Hollywood Reporter magazine there could be 'two, three, even four Kardashian' spin-offs.
But top TV executive, who was named as the second most powerful woman in Hollywood by the magazine, admitted the current crop of Kardashians was 'too fragile' for the network.
The family, run by matriarch Kris Jenner, have come under a blitz of negative publicity following Kim Kardashian's 72 marriage to Kris Humphries.

The wedding was reported to have generated up to $18m in income for the Kardashians although mum Kris denied they had profited.
Hammer told the Hollywood Reporter the marriage was not a stunt.
But in a lengthy interview profiling her career Fuller also admitted that E! would not be so reliant on Kim Kardashian and the staged antics of her sisters.
She said of the show: 'I think it will have its own life expectancy and we'll go along with it and help hone what's right for E! and what's not right for E! as we develop a whole other world.'

'I think true Kardashian fans know that a bigger than life mistake can be made easily in their world. Everything they do is bigger than life.. it just part of their DNA.'
Fuller, who also heads up the USA network and SyFy Channel for NBC Universal, was named joint second as the most powerful woman in Hollywood.
Anne Sweeney, President of ABC Television, was named the most powerful woman in entertainment.
