Yesterday, we learned that the reality star may be facing jail time as a result of the fatal car accident she allegedly caused back in February.
Of course, throughout the many struggles she's endured over the past year, Caitlyn has repeatedly claimed that the support of her family is the most important thing in her life.
While we're sure her daughters and stepdaughters are still there for Caitlyn in spirit, they're not as present in her life as they once were, as evidenced by the fact that the whole family is currently vacationing in St. Bart's - without Caitlyn.
Of course, separate family vacations are the norm following any divorce, but insiders say the Kardashian clan had vowed to buck the trend and keep Caitlyn in their lives in every way.
That all changed with the start of the ongoing Caitlyn and Kris Jenner feud.
Kris and Caitlyn met for the first time last month, and it was rumored that they had buried the hatchet. Now, for reasons that no one quite understands, the bad blood is at an all-time high, and Kris reportedly insisted that Caitlyn not be invited to St. Bart's.
"Caitlyn is really bummed right now because this is the first big family trip that they all went on in over 20 years that she was not a part of" an insider close to the family tells Radar Online.
"There is more animosity than ever before between Caitlyn and her ex Kris Jenner...Caitlyn was not surprised at all by not being invited on the family trip to St. Bart's. But it really did hurt her that she wasn't included.
"No one even told Caitlyn that her daughters Kylie and Kendall were going on the trip. It's just another reminder that Cailtlyn has been cut out of the girls' lives, and it really stings."
