During tonight's ESPY Awards, Caitlyn will be joined by many members of his family. However, the Keeping Up With The Kardashians matriarch will reportedly not attend, nor will she be mentioned by the transgender reality star.

“As of Wednesday afternoon, she is not planning on mentioning her at all,” a source told Radar Online on Wednesday. “Caitlyn has prepared a speech and she has been rehearsing it and reading it to some of her children to make sure that it sounds right, but she is an absolute wreck right now and has had trouble sleeping for like the past week because she is so nervous about the ceremony. Caitlyn is a perfectionist and she just wants everything to run smoothly."

Caitlyn and Kris were married for more than two decades, and according to a second source, Kris, the mother of Caitlyn's youngest daughters, Kylie and Kendall, was hoping to be included in her big night.

“She would have like to have been invited,” a friend of Kris' told Hollywood Life. “She’s spent nearly half of her life with Caitlyn, loving one another, raising children, making a lifetime of memories and this is the treatment Kris is getting. Shame on Cait. She needs to stop being such a diva.”

The ESPY Awards airs tonight at 8 p.m. on ESPN.
