Scott Disick has heartbreaking reaction to ex Kourtney Kardashian’s over-the-top THIRD wedding to Travis Barker in Italy

"He just isn't there emotionally yet. Kourtney wouldn't want him there if he’s going to be weird about it."

Kourtney and Travis had a Las Vegas ceremony last month, hours after the rocker performed at the Grammys and without obtaining a marriage license.

At the weekend, the lovebirds tied the knot for real with a courthouse wedding in Santa Barbara.

Scott reportedly had no idea about Kourtney's Santa Barbara wedding and is "upset" that he wasn't in the loop.

"Scott is very upset and didn’t know about the Santa Barbara wedding ahead of time," the insider said.

"To find out on social media and through friends was upsetting for him. He's still not happy about everything, but he's trying to remain supportive."

Kourtney's three kids Mason, 12, Penelope, nine, and Reign, seven, were noticeably absent from the ceremony.

Instead, the trio spent the day hanging out by the pool with Scott.

As for Kourtney's Italian wedding, it will reportedly be a lavish "over-the-top" affair.

"Kourtney’s big wedding will have the entire family there and be so over the top," the source told ET.

"She is so excited. It will be a bigger moment with all her sisters, family, friends and Travis’ family and friends in Italy."

Earlier this week, Kourtney was slammed for not inviting her three kids to her courthouse wedding.

One asked on Instagram: "Why aren’t her kids around? You’d think they’d be a part of her special day. It’s like her kids come second these days."

Another wrote: "Her kids were left out of the Vegas wedding too wtf?"

A third posted: "I feel so bad for those poor children. Imagine not seeing your mom getting married."
