Kourtney Kardashian rocks cozy pajamas for ‘perfect’ New Year’s Eve… as she flashes her diamond Mrs. Barker and Rocky necklaces

Kourtney Kardashian enjoyed a low-key New Year's celebration.

The mother of four, who welcomed son Rocky with husband Travis Barker in early November, wore glasses with NYE written above them in gold.

Kourtney, 44, added a number of diamond necklaces, including one that read “Mrs. Barker,” as well as one that said “Rocky” for her son.

The stunner captioned the photo: “A perfect, fun New Year's Eve in pajamas.”

On December 22, Kourtney and husband Travis, the drummer for the band Blink-182, shared the first glimpse of their son Rocky.

Rocky was born on November 1, 2023 at Cedars-Sinai Medical Center in Los Angeles.

The lovebirds cradled their son in the snaps shared on Instagram.

In one image, Kourtney breastfed Rocky while wearing a black hoodie and matching sweatshirt.

Travis, 48, wasted no time cradling Rocky in his arms and wearing the same look as Kourtney: black hoodie and matching sweater.

In another image, Travis planted a sweet kiss on their son.

Rocky Thirteen is Kourtney and Travis' first child together.

Kourtney has three children with ex-partner Scott Disick: sons Mason, 13, and Reign, eight, and daughter Penelope, 11.

Travis is father to son Landon, 19, daughter Alabama, 18, and stepdaughter Atiana, 24, with ex-wife Shanna Moakler.

Kourtney and Travis publicly announced her pregnancy in June, while paying tribute to a Blink-182 music video – All The Small Things.

In the music video, a woman holds up a sign that reads, “Travis, I'm pregnant.”

Kourtney recreated that at a Blink-182 concert in June in Los Angeles for an adorable public service announcement.

In September, Kourtney had to undergo life-saving fetal surgery.

Days after she was released, she took to her Instagram to thank the hospital staff, as well as Travis for being by her side.

“I will forever be grateful to my wonderful doctors for saving our baby's life. I am eternally grateful to my husband, who rushed to my side after the tour to be with me in the hospital and then take care of me, my rock.'

Adding: 'As someone who has had three very easy pregnancies in the past, I was unprepared for the fear of rushing into fetal surgery. I don't think anyone who hasn't been through a similar situation can understand that feeling of fear.

'I have gained a whole new understanding and respect for the mothers who had to fight for their babies during pregnancy.'

In December 2022, Kourtney revealed that she had stopped IVF ten months earlier because, among other things, it caused her to fall into a deep depression.

She had been very open about her struggles with IVF on Hulu's The Kardashians.

Kourtney and Travis conceived Rocky naturally, she revealed in an interview with Fashion in November 2023.

'We just got pregnant naturally. It was an indescribable feeling. Shock, then super happy, fear comes in, worry, but I remember having gratitude.”

Kourtney and Travis started dating in 2020 after almost 10 years of friendship; Travis was also her neighbor.

They became official on Instagram in February 2021 and engaged in October 2022.

They got married in May 2022 at a courthouse in Santa Barbara and headed to Portofino, Italy, a week later to have a lavish wedding at the Dolce & Gabbana mansion in front of their friends and family.
