Kendall Jenner's boyfriends has been revealed. The model had a non-negotiable precedent about when her boyfriends could actually appear on camera. "Kendall's always had this rule – she felt like she had to be with someone for at least a year before she let them be a part of the show, because she doesn't always know what people's intentions are," Farnaz Farjam, executive producer of the popular reality TV show, told Bravo's The Daily Dish.
