Kourtney Kardashian has broken her silence since welcoming her baby boy – as the star posted an extremely risque tribute to husband Travis Barker on his 48th birthday on Tuesday.

The reality star, 44, who welcomed her son earlier this month, showed off her ample cleavage and baby bump in just a pair of jeans for the throwback shoot, while Travis grabbed onto her bust.

Travis was also seen putting his hand down her trousers as the pair embraced before posing with his hand on her stomach.

Kourtney wrote: ‘To my husband, my soulmate, my best friend, my lover, my daddy to our baby boy, my everything…

‘I wish you the happiest birthday. You make all of my dreams come true and I feel so blessed to have you by my side. I love you beyond words, forever.’

Oh my: Kourtney Kardashian has broken her silence since welcoming her baby boy – as the star posted an extremely risque tribute to husband Travis Barker on his 48th birthday

A source recently told People that Barker is ‘obsessed with their baby boy’ and Kardashian feels ‘over the moon about her son’s arrival’ after ‘pregnancy took a stressful turn towards the end.’

A source also told the outlet that she is ‘happy to just be able to snuggle her baby boy now’ and ‘feels so blessed.’

Overall, the parents ‘are both elated’ by the arrival of their ‘beautiful baby boy.’

Neither Kardashian, Barker, or their families have posted to share photos of their infant.

The new dad was spotted at his studio in Los Angeles on his birthday with his friend, Limp Bizkit frontman Fred Durst, 53.

Barker was also pictured getting his classic car washed while enjoying time at his studio. He rocked a black and red graphic tee, a matching black beanie, and black sunglasses.

It has been a long road for the famous couple as they spent two years trying to conceive the baby.

Kourtney tried IVF several times and she did not get pregnant until she finally stopped all treatments late last year. The Keeping Up With The Kardashians veteran has said in the past that she feels getting pregnant naturally was ‘God’s plan.’

In September, the POOSH founder revealed she had ‘terrifying’ fetal surgery to save her unborn baby’s life.

Appearing on his in-laws’ Hulu series The Kardashians, he also disclosed that Kourtney’s due date was on Halloween.

On Saturday morning Travis’ Insta Stories played host to some plugs for his clothing line Famous – but no mention of the baby.

This is a fourth child for Kourtney as she already has three children — Mason, 13, Penelope, 11, and Reign, eight — with ex-boyfriend Scott Disick, 40.

And it is a third child for Travis who shares two children — Landon and Alabama — with Moakler, 48. The rocker also considers Shanna’s daughter with former boxer Oscar De La Hoya – 24-year-old model Atiana De La Hoya – his child.

In mid-October, she told Vanity Fair Italia she had conceived naturally after failed attempts at IVF for two years.

‘I just say: how could you question God’s plan? Because that’s how I see this pregnancy, which came when both Travis and I weren’t even thinking about it anymore and a year after we stopped IVF,’ she said.

Kourtney revealed last December that she’d officially stopped her IVF journey 10 months prior after she said it caused her to spiral into a deep depression among other symptoms.

Upon learning she needed to undergo fetal surgery to save her unborn son’s life, Travis flew home from his tour to be by her side.

‘It was terrifying. I feel that sooner or later I will go into detail because I hope that it could help others, but I don’t feel ready yet because it was really frightening,’ the star said.

Kourtney revealed her pregnancy news to the public in June while Barker performed on stage at his concert. She held up a sign that read: ‘Travis, I’m pregnant.’

It was a nod to the band’s iconic All The Small Things music video, in which a similar sign appears.

After catching a glimpse of his wife’s message, Travis jumped down off the stage, made his way towards her and the couple shared a passionate kiss.

She later confirmed the news on her Instagram Story by sharing a video of the surprise reveal.

Kourtney and Travis became romantically involved in late 2020 after nearly a decade of friendship. They made their relationship Instagram official in February 2021 and were engaged by that October.

The couple wed at a courthouse in Santa Barbara in May 2022 before jetting off to Portofino, Italy a week later to hold a lavish wedding at the Dolce & Gabbana mansion in front of their friends and family.

Kourtney has been open with fans about her attempts to conceive a child with Barker through in vitro fertilization.

In 2022, Kourtney first detailed her struggle with IVF on Hulu’s The Kardashians.

In the episode, Kourtney was at her Calabasas home as mom Kris Jenner came to visit, asking how the doctors went, as Kourtney responded: ‘Awful.’

Kourtney revealed in confession that their doctor took them ‘down this road of doing IVF, and it hasn’t been the most amazing experience.’

She also claimed that the ‘medication that they have been giving me, they put me into menopause, literally into menopause.’

Along with the Kourtney said that it also put her into a depression and caused weight gain.

‘I think because I’m so clean and careful about what I put into my body, it’s just like having the complete opposite reaction and working as a contraceptive instead of helping us,’ she told audiences at the time.

‘I have everything in the world to be happy about. I just feel a little bit off and not like myself. Super moody and hormonal, like I am a lunatic half the time.’

In December 2022, she confirmed to fans that she’d officially stopped treatment 10 months earlier and was only just ‘getting my energy back.’

She told The Wall Street Journal that she ‘took a break to just focus on our wedding and getting married’ — which took place in May 2022.

In the season premiere episode of season three of The Kardashians, the mother-of-four further discussed their choice to discontinue IVF and how she’d frozen her eggs in her 30s.

‘We would love a baby more than anything but I just really believe in what God has in store for us,’ she explained.

Kourtney had ‘seven frozen eggs from years ago before Travis’ that those around her had pushed her to get.

‘When I was 38 or 39 everyone was like pushing me to do that and most of mine didn’t survive the thaw because eggs are one cell and none of them made it to an embryo.’

Kourtney was always aware that ‘freezing of the eggs is not a guarantee’ that she would get pregnant.

She told her sister Khloe that her and Travis already ‘have a full, blessed life’ without a child, so they were not letting it get them down.

‘All the thing that came with IVF took a toll on me physically. My health is still impacted because it’s hormones. And also mentally it took a toll,’ she explained.

‘So, I think just being happy is most important and being a good parent to my kids. We are just embracing that whatever is meant to be will be.’

Kourtney previously said that motherhood is her ‘favorite role in life’ and that it ‘gives me purpose.’
