But my script is so long... I'm not an actress." Her performance was met with negative reviews from critics. In September 2012, she and younger sister Kim created another spinoff reality television series, Kourtney and Kim Take Miami, which began airing in January 2013. It features their mother Kris Jenner and sister Khloé Kardashian.
