Kourtney Kardashian's daughter started crying and hung up on her when she told her that she was engaged to Travis Barker

• Kourtney Kardashian's daughter cried when her mom told her on the phone she was engaged.
• Kourtney and Scott Disick's children weren't present when Travis Barker proposed to her.

Kourtney Kardashian's daughter Penelope hung up on Kourtney after she told her that she and Travis Barker had gotten engaged.

Episode four of "The Kardashians," which aired Thursday, focuses on Kourtney and Barker's engagement, which took place at the Rosewood Miramar Beach hotel in Montecito, California. While Barker's children, and other members of the Kardashian-Jenner family, were present, Kourtney's three kids (Mason, 12, Penelope, 9, and Reign, 7) and their father Scott Disick weren't involved in the event.

After the proposal, Kourtney goes to a separate room to call her daughter Penelope.

"We got engaged," Kourtney tells her daughter on the phone, showing off her ring. Penelope then begins to cry on the phone.

"Penelope, why are you sad, baby?" Kim, who was sitting next to Kourtney during the call, asks Penelope.

"Hang up," Penelope replies, ending the call.

Kourtney's other children had more muted reactions, with her son Reign telling Kourtney that the news was "not exciting."

"I do wish that my kids were here," Kourtney says in a confessional. "I think it would have made them feel more included in the decision, kind of, and part of the surprise. I know that my mom made that decision, and it probably wasn't her best."

Speaking to all four of her sisters, Khloé likened Kourtney's children's response to the engagement to the adjustment that the four Kardashian siblings went through after their mother, Kris Jenner, remarried Caitlyn Jenner.

"I think they think they're losing their dad. I don't think they're losing their mom," Khloé said. "They think their dad is gone and you're replacing him. When you're a kid, you think you have to pick one. P's reaction is understandably ok, but there's nothing wrong with Travis."

Later in the episode, Khloé speaks with Disick about his feelings about the engagement, and their children not being present for the proposal.

"They were upset," Disick says of his and Kourtney's children. "They didn't understand why they were watching TikToks of his kids there, and they weren't there. Hopefully, they'll be invited to the wedding."

Kourtney and Barker, who first met in 2006, started dating in early 2021 got engaged in October 2021. The two married in a non-legal ceremony in Las Vegas on April 4, 2022, hours after attending the Grammy Awards together.
