Los Angeles: Reality TV star Caitlyn Jenner reportedly had a fall out with the Kardashian clan and she is now "lonelier than ever", according to a source. The 66-year-old transgender activist's relationship with the Kardashians is the "worst" ever now, radaronline.com quoted the source as saying. "Caitlyn's relationship with the Kardashians is the worst that it has ever been. Sadly, the only ones who seem to have any time for Caitlyn anymore are her daughters Kendall and Kylie... Even Kim (Kardashian) seems too busy for her nowadays," the source said. The insider also said that Caitlyn is not handling it very well. "She has just been keeping to herself and has been pretty down lately," the source said. Caitlyn, who was named Bruce before her transition, is a retired Olympic gold medal-winning decathlete, and has six children from marriages to ex-wives Chrystie Crownover, Linda Thompson and Kris Jenner. Since 2007, Caitlyn has appeared on the reality television series "Keeping Up with the Kardashians" with Kris, their daughters Kendall and Kylie, and step-children Kourtney, Kimberley, Khloé and Rob Kardashian. Caitlyn revealed her identity as a transwoman in April 2015, publicly announcing her name change from Bruce to Caitlyn in July 2015. Her name and gender change became official on September 25 last year.
