For the occasion, the mother-of-four looked nothing short of sensational in a plunging blazer with nothing under it, apart from a black bra.

Kourtney Kardashian and husband Travis Barker packed on the PDA at the 2024 as she attended her first public event since welcoming their baby boy, Rocky Thirteen, on November 1

While arriving to the star-studded event, held at the Peacock Theater in Los Angeles , on Monday, the reality star, 44, and drummer, 48, were seen sharing a passionate kiss

The duo, who sported matched in black suits and oversized shades, appeared as in love as ever while gazing adoringly at one another as photographers snapped their photo

The reality star and her man haven’t been seen in public much since she gave birth to her fourth child, just less than three months ago.

Their latest sighting comes just days after a source told DailyMail.com that the couple ‘frustrated’ by his ‘jealous’ ex-wife Shanna Moakler’s ‘inappropriate’ claims about them.

This comes after the model, 48, ripped into the Blink-182 rocker in a recent interview, in which she accused him of being a womanizer and spoke about his addiction issues during their time together.

She also accused Kardashian of wooing her children with expensive gifts and experiences that she cannot afford to provide for them.

Travis, 48, and Kourtney, 44, reportedly believe Shanna is ‘hurting’ the children with her latest attack, which also saw her brand the Kardshians ‘disgusting.’

‘Travis wants to move on from all the endless chatter and anything she says negatively about him or Kourtney,’ an insider told DailyMail.com exclusively.

‘Travis has formed an emotional callus after all these years. He only wants to do what is right for their kids, but every time she talks about him he just gets frustrated that she bashes him.

‘He is acting the way he does with his kids because that is their relationship, it is not to one-up Shanna. Kourtney only respects her since she is the mother of his children, but a friendship is out of the question.

‘They both try to go through their day not thinking about her, but when she opens her mouth to give them s**t, it is a temporary annoyance that they have to just let roll off of them. They refuse to let her words consume them no matter how outlandish.’

The musician has son Landon, 20, and daughter Alabama, 18, with Shanna, who he was married to for four years from 2004. He is also a stepfather to her 24-year-old daughter Atiana with Oscar De La Hoya.

A second source claimed Kourtney is annoyed at her for ‘hurting’ the children with her verbal attacks.

‘Kourtney is a private person, and she thinks Shanna calling out her marriage and the relationship with Shanna’s kids is inappropriate.

‘She knows that Shanna is jealous because Kourtney has a life with Travis and a strong bond with Shanna’s kids. She didn’t need to go and put her on blast and feels it is only hurting their children.’

The insider continued: ‘Shanna and Travis’ kids are happy with them, and it is not Kourtney’s fault that they have all the money and luxuries that the kids have grown used to.

‘Kourtney is being the mom she always has been, and she is providing for his kids as if they were her own.’

In her scathing interview on Bunnie XO’s Dumb Blonde podcast, Playboy model Shanna fumed: ‘He did me pretty dirty. His drinking is a problem. His womanizing, his addiction.’

She went on to slam Travis’ wife Kourtney’s family as ‘disgusting’ before she accused Travis of ‘parental alienation’ when he got together with the Poosh founder.

She moaned: ‘You’re disgusting. I removed myself so that they couldn’t bond with my children over hating me.

‘Go do what you guys need to do and when you’re ready, I will be here loving you unconditionally.

‘And I will be here as your mother, and I will wait. And that’s what I did.

‘There are people that don’t like that family, don’t watch their show and don’t give a [damn] what Kim [Kardashian] is doing with her [butt].’

The pair’s baby boy, Rocky Thirteen, was born on November 1

Shanna – who was married to Travis from 2004 to 2008 – claims Travis uses his wealth to impress his children and to make out he is the better parent.

She continued: ‘When Travis got with Kourtney, there was some parental alienation going on there, where Travis — even when we weren’t together — always wanted to be the “super dad.”

‘”I’m the best parent. I’m the this and that,” and I’m like, “Bro, you win. Like, you’re the winner here. You have all the money and you have all this. You’re the winner.”‘

She believes her children were ‘caught up’ in the Kardashian’s ‘glitter and fame’ – something she feels she can never compete with.

‘I think there was a lot of glitter and fame and they watched them on TV and now their dad is dating one and they’re going to be on the show,’ she said. ‘And I think they got caught up in that, which young kids would do.

‘They’re buying them Prada, and they’re buying them gifts, and they’re going to these events and they’re meeting Kanye and, you know, all this big stuff.

‘I can’t give them that. I don’t have that. I don’t have access to that. I don’t have the money to do that. I can’t buy you guys Prada every other week and stuff. I don’t. I can’t do it.’

She added: ‘My house isn’t a mansion like, Travis’. I don’t have a movie theatre. I don’t have golf carts for you kids to drive.’
