Kourtney Kardashian paid tribute to husband Travis Barker on Sunday with a gushing Father’s Day post on Instagram.

The 45-year-old reality television personality uploaded a slew of intimate photos of Barker, 48, with their son Rocky, who was born seven months ago.

The POOSH founder wrote in a gushing caption: ‘Happy Father’s Day @travisbarker!! Beyond grateful for the Dad that you are to our baby boy, and all of our kids.

‘You keep us safe and protected and take care of us. Having a family with you is heaven. Happy to celebrate you!’

Kardashian also shares three children with 41-year-old ex-boyfriend Scott Disick, who received a ‘Happy Father’s Day’ banner of balloons.

The exes share Mason, 14, Penelope, 12 in July, and Reign, nine.

Scott posted a picture of his shiny silver balloons — which included MPR balloon initials representing his kids’ names — and wrote in a caption to his 29.2 million Instagram followers: ‘Thanks my loves 4 making this day what it is to me! ❤️.’

Included in the mother-of-four’s roundup of photos was an image of the Blink 182 drummer lying on a striped towel as he held their son on his chest.

The musician also cradled the little one while on a private flight and backstage at one of his shows.

Another beachside snapshot featured the baby’s dangling legs as Travis held him at the shoreline as the sun set.

Kardashian’s son Reign, dressed in big denim shorts, was also in the capture.

Kourtney, who is Kris Jenner’s firstborn child, also remembered her late father Robert Kardashian on Sunday.

Via her lifestyle brand POOSH’s Instagram account, she shared a throwback image with her dad, who was known for being one of OJ Simpson’s attorneys and close friends.

In addition to being a stepdad to the bombshell’s three children with Disick and a new dad to their baby, he also shares son Landon, 20, and daughter Alabama, 18, with ex-wife Shanna Moakler.

And Barker is still active in his stepdaughter Atiana De La Hoya’s life — Moakler’s 25-year-old daughter with ex Oscar De La Hoya.

Kourtney and Travis tied the knot in 2022, in an elaborate ceremony in Italy that was later featured in a Hulu special.

They shocked fans in February 2021, when they first went public with their romance after several years of friendship.

The couple struggled to conceive via IVF using Kardashian’s frozen embryos, and later stopped the physically taxing process to focus on wedding planning.

The Lemme supplement founder announced that she subsequently became pregnant naturally in June 2023.

Rocky Thirteen Barker was born in November 2023.
