Reality TV stars Kendall and Kylie Jenner have revealed they are working on their own mobile game. Kendall, 19, and 17-year-old Kylie have opted to take a lead from their half-sibling Kim Kardashian, who has already developed her own game. Kendall wrote on Instagram. Kim, 34, launched her own game for mobile phones, "Kim Kardashian: Hollywood", last year, allowing members of the public to pretend to be a rising celebrity friend of the reality TV beauty.
