Kourtney Kardashian and Travis Barker got married in a lavish Italian ceremony.

Everybody was there - almost, and it was noticed by many.

Rob Kardashian missed her eldest sister's wedding because, as reported, he doesn't like to be seen that much as he values his privacy.

But one person who was a staple in every Kar-Jenner event was Caitlyn Jenner, who was reportedly not even invited to the nuptials.

An insider revealed to TMZ that Kris Jenner's former husband never got an invitation to the wedding because they don't see or talk to each other that much.

Instead, the former Olympic champion headed to Barcelona to cheer on her team Jenner Racing and even celebrated one driver, Jamie Chadwick.

However, it doesn't mean Caitlyn is okay with missing Kourtney's important day.

Another insider revealed to The Sun that she is "Crushed" about not being invited and has been feeling "very alone."

Thankfully, though, she has her partner and friend Sophia Hutchins by her side.

The source went on to say that the wedding was already intimated that Kourtney and Travis Barker only invited immediate family and a few friends.

However, not inviting the 72-year-old wasn't because she's not part of the show anymore - but because they're not "super close" right now.

Where Was Scott Disick During Kourtney Kardashian's Wedding?

Many fans also wondered where Scott Disick might have been during Kourtney Kardashian's wedding to Travis Barker.

According to an insider close to the "Flip it Like Disick" star, he was indeed invited to the wedding but decided not to go, choosing his mental peace instead of the chaos and seeing the happiness of his ex.

Additionally, Kourtney would also want to have the moment to be about her and Travis, and with Scott being there, the dynamic would be weird and wouldn't feel right, the source added.

Scott still hasn't moved on from Kourtney, with the source saying it's been easier now for him to cope after seeing Kourtney and Travis celebrate their love.

"It's not as hurtful, and he's getting through it."

Days after the wedding, Scott immediately reunited with his three kids, Mason, Penelope, and Reign, with the former reality star sharing a series of photos on his Instagram Stories.

"I got my baby," he added. "Got my crew with me."
