Tensions appeared to be high once again between Kris and Kourtney at the Poosh founder’s party to reveal her son’s gender.

During The Kardashians’ season finale, Kris was caught asking Kourtney and her husband Travis Barker: “What’s the [baby’s] name?”

The couple – who called their child Rocky Thirteen Barker – was walking past holding hands and stopped.

Travis turned back and replied: “Rocky.”

Kris blurted out in shock, “Oh!” before pausing and saying, “Okay!” as Travis said with a serious expression: “Yeah.”

The matriarch then added unconvincingly: “I love it!”

She let out a long, awkward laugh as Kourtney and Travis turned and walked away in silence.

The tense moment was caught by a group of cameras who had gathered around.

Earlier in the episode, Kris and Khloe admitted they felt hurt that they weren’t included in Kourtney’s pregnancy announcement.

Kourtney had revealed she was expecting a fourth child by holding up a “Travis I’m pregnant!” sign at a Blink-182 concert in June.

During the scene, Khloe said she confronted Kourtney and told her their feelings were hurt for not being given the heads up and Kourtney told Khloe “I forgot.”

Kris replied: “She forgot she had a family.”

KOURT HITS BACK

In a confessional, Kourtney said: “I truly just did not think of inviting them to the LA concert and didn’t think they would care to come.

“I did tell Khloe about it and she tried to get me to change it to San Diego, but it’s not about you.

“It was about me and Travis, not about anything else. This is why I don’t invite them to stuff because it’s not about you! Everything always becomes about them and their complaints.”

She also complained that they were both “controlling.”

Kourtney has been laying low since she welcomed her first child with Travis in early November.

The Hulu star was rushed into emergency fetal surgery in September while late into her pregnancy.

The procedure typically involves performing surgery on the unborn baby while they are still in the womb.

Kourtney has three other kids with her ex Scott Disick – Mason, 13, Penelope, 11, and Reign, 8.
