The website claims Khloe called Caitlyn herself to let her know she wouldn't be at the dinner party.
In fact, she even sent the transgender star a beautiful bouquet of pink and white roses to make up for her absence.
An Instagram snap of Caitlyn surrounded by flowers appears to feature Khloe’s bouquet.
Caitlyn celebrated her big day alongside her daughters Kylie and Kendall Jenner, son Brander Jenner, and stepdaughters Kourtney and Kim Kardashian at Nobu.
Caitlyn’s youngest son , Brody Jenner was also noticeably absent, as was Khloe’s brother, Rob.
Earlier on this week it was reported that Caitlyn decided not to attend an event at the last minute after learning Khloe and former son-in-law, Scott Disick would be in attendance.
