Caitlyn Jenner Upset About Her Father’s Day Celebration; ‘Keeping Up With The Kardashians’ Patriarch Hurt Over Three Kids’ Absence?

Caitlyn Jenner is reportedly upset about her Father's Day celebration. According to a report from Radar Online, the "Keeping Up with the Kardashians" patriarch was hurt over the absence of three of his kids last holiday weekend.

Photos of Caitlyn Jenner's Father's Day party showed her looking happy with her children. However, a source claimed that the reality star was very sad that Kylie Jenner, Rob Kardashian and Kourtney Kardashian did not show up to accommodate her request.

"[They] all were invited to spend the day with her, and it was their choice not to go," said the source.

Caitlyn Jenner's youngest child, Kylie Jenner, reportedly chose to spend Father's Day with her rumored boyfriend Tyga and his two-year-old son, King Cairo.

"Caitlyn does not like Tyga and does not approve of this relationship," an insider pointed out.

The 17-year-old did post a Caitlyn Jenner Father's Day tribute online, which the transgender reality star appreciated.

"Caitlyn did appreciate Kylie's sweet post and hopes that time will heal all wounds," a source said.

Another no-show was 28-year-old stepson Rob Kardashian. The troubled TV personality allegedly only texted Caitlyn Jenner last Father's Day.

As for Kourtney Kardashian, the 35-year-old mother of three supposedly did not attend Caitlyn Jenner's Father's Day celebration out of concern for her children. She and partner Scott Disick are allegedly anxious about discussing the family patriarch's sex change to their children, namely Mason, 5, Penelope, 2 and Reign, 6 months.

"Kourtney and Scott would confuse Mason if they introduced their kids to 'Grandpop Bruce' on Father's Day," an insider revealed.

"They spent the day with their own family and will face this issue when they are ready."

"Caitlyn is devastated by them all not being there, but accepts their reasoning, and they know that she will be there when they are ready to accept the transition," the source said.
