Kim Kardashian West 'Heartbroken' After Upsetting Kanye By...

On Sunday's episode of Keeping Up With the Kardashians, Scott Disick came to terms with his relationship with Kourtney Kardashian while Kim Kardashian West accidentally missed an important event for her husband.

The episode started off with Kim making plans for she and Kourtney to fly out to Iceland for Kanye West's music video shoot. While there, they would celebrate Kourtney's birthday with a few friends – and sans Disick and the kids.

When Kourtney broke the news to Disick, he got extremely upset that they wouldn't be spending her birthday together.

"I thought I'd be there to give her a hug or a gift," Disick told the cameras during an interview. "It's sad for me to hear."

Later, he drove over to Kris Jenner's house to talk about his plan to fly to Iceland to surprise Kourtney, but she convinced him that it wasn't the best idea.

"Later, if we worked things out, I would've hated to miss things like this," Disick, 33, told Jenner. "We had all of these memories, now they're stopping one by one."


Meanwhile, in Iceland, Kim and Kourtney, 37, were off exploring and taking trips to a tomato farm and a hot spring where they began to discuss Kourtney's current relationship with Disick.

"We are just doing our best to co-parent and getting along," Kourtney told Kim. "I don't want to spend time with him one-on-one ... that's not what I want right now, and it's not good."

Meanwhile back in Los Angeles, the news of Rob and Blac Chyna's engagement and baby started to really set in with the Kardashian family – including Khloé, but it took some convincing a little help from Lamar Odom.

While Khloé, 32, was relaxing at her house, Odom, 36, walked in with Rob, which awkwardly forced the siblings to finally have a sit-down conversation about their lingering issues.

"This is kind of awkward for Rob and Lamar to walk in the theater like nothing has happened," Khloé said in an interview, followed by her ex breaking the ice by asking Khloé if she would like to go out to eat with Rob and Blac Chyna.

"No that's not part of the plan, it's not Blac Chyna too," she said to them. "No."

Rob, 29, wound up giving in and told his sister that it could be just them and Odom if that works for her – which she agreed too.

"Rob and I have a long way to go but I want my relationship back with my brother," she told the cameras.
