Travis Barker and Kourtney Kardashian‘s newborn son’s name, Rocky Thirteen, has a few very special meanings behind it – including a link to his older sibling.

The Poosh founder, 44, has reportedly ‘given birth to her baby boy,’ sources informed People – whom she shares with the Blink-182 drummer, 47.

In regards to the baby’s very unique name, Barker previously opened up about the moniker during an interview with his daughter, Alabama, for Complex’s GOAT Talk video series, which was released this past July.

The musician stated at the time, ‘Rocky George played guitar for Suicidal Tendencies, and 13 is just the greatest number of all time.’

He also took inspiration from the Sylvester Stallone-starring movie Rocky, which he described as ‘the greatest boxing movie of all time.’

Alabama then expressed that the idea of her father naming his new son Rocky Thirteen was ‘so bad,’ about which he jokingly agreed.

When Barker asked his daughter for other ideas, she listed Audemars, Cloud, Patek and Milan as potential names.

While the name, Rocky Thirteen, drew inspiration from iconic films, his older sister’s name, Alabama, was also named after a character from the 1993 movie, True Romance.

However, her initial feelings towards the name of her baby brother have since changed, which she admitted during an interview with E! News earlier this week.

‘It’s a cool name. We all have very authentic, weird names,’ she explained to the outlet, and gushed, ‘I just think having another family member is always awesome. And getting to know a new person, it’s gonna be so fun and so exciting.’

According to People, Kardashian gave birth earlier this week. DailyMail.com has reached out to a representative for comment.

Earlier this week on Friday, Travis was notably spotted inside his vehicle as he arrived to Cedars-Sinai Medical Center in Los Angeles, further fueling speculation that the TV personality has already given birth to their son.

The reality television personality also shares her sons Mason 13, and Reign, eight, as well as her daughter Penelope, 11, with her former partner, Scott Disick.

Barker also shares his son Landon, 20, and Alabama with his second wife Shanna Moakler, to whom he was married from 2004 until 2008.

The performer also serves as a stepfather to his wife’s eldest child Atiana, 24, whose biological father is Oscar De La Hoya.

The lovebirds – who dressed up as Beetlejuice and Lydia Deetz for Halloween – began dating in 2021, and they tied the knot in May of last year.

The reality television personality revealed that she was pregnant during a Blink-182 concert that took place this past June.

Before their son was born, Kourtney notably took to social media in September to update her fans and followers that she underwent emergency ‘fetal surgery’ and gave a special shoutout to her family and doctors.

She also uploaded a close-up, black and white photo of her hand holding her husband’s as she rested in a hospital bed.

The Poosh founder expressed, ‘I will be forever grateful to my incredible doctors for saving our baby’s life.’

‘I am eternally grateful to my husband who rushed to my side from tour to be with me in the hospital and take care of me afterwards, my rock. And to my mom, thank you for holding my hand through this,’ she sweetly added.

Kourtney admitted that she hadn’t been ‘prepared’ for ‘the fear of rushing into urgent fetal surgery’ after experiencing smooth pregnancies in the past.

Barker jumped to the comment section in response to his wife’s post and also expressed his gratitude that all was well by adding, ‘God is great.’

While talking to Vanity Fair Italia last month in October, she opened up about conceiving naturally following IVF attempts in the past.

‘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.’
