Tristan Thompson isn’t about the circus that Khloe’s soon-coming baby birth is predicted to be.

According to Radar Online, the Cleveland Cavaliers center has issued his baby mama an ultimatum: if the Kardashian clan’s going to be in the delivery room, he won’t be.

A source told the website Thompson was shook by the scene made by Khloe’s family during Kim’s surrogate’s birth of their child Chicago in January.

“Tristan freaked out after that circus,” the source said. “The family didn’t see the pushing part but they were in the room vying for space after Chi came out. They were a loud, intrusive bunch and Tristan told Khloé not to even think about having them present when their baby is born.”

It’s a tough choice, but apparently, Khloe made her decision.

“Khloé wants her family to be with her — but she also wants Tristan to hold her hand through the process,” the insider said. “So if those are her choices, she’s going with Tristan. She told her mom Kris, ‘Sorry!’

“The Kardashian women can hang out in the waiting room, but under no circumstances will they be allowed in the birthing suite!”

Wow. We’ll have to see how this one plays out.
