Sources told The Daily Mail that Jenner "has been advised by friends in the fashion industry that reality TV could damage her modeling career." But because she's contractually bound to finish off the series, the 18-year-old star has allegedly taken other precautions.
"Kendall had the option to pull out of any other potential shows and that's exactly what she's done," said the insider.
Jenner's modeling career -- which took off this year following her appearances at Marc Jacobs Chanel and Givenchy shows in March -- has kept her from appearing in several of the new episode of the E! reality series.
Earlier this year, it was reported that Jenner's half brother Rob Kardashian also decided to pull back from the show because he felt like it had "ruined" his family, and that his mother Kriss Jenner "is always on the look out for the next big deal for one of her daughters."
"His significant weight gain has only added to the stress in his life," added the source. "He has been working out but has very bad eating habits. He just feels very alone."
