All the small things about Kourtney Kardashian and Travis Barker's baby boy have been uncovered.
The Kardashians star and the Blink-182 drummer welcomed their son—named Rocky Thirteen Barker—at Los Angeles' Cedars-Sinai Medical Center, according to a birth certificate obtained by E! News. And though Halloween is one of the couple's favorite holidays, their newborn missed this year's spooky season by mere minutes—as he was born exactly on midnight Nov. 1.
The little one joins a large blended family that includes Kourtney's three kids Reign Disick, 8, Penelope Disick, 11, and Mason Disick, 13, with her former partner Scott Disick, as well as Travis' daughter Alabama Barker, 17, son Landon Barker, 20, and stepdaughter Atiana De La Hoya, 24, with his ex-wife Shanna Moakler.
Still, Rocky arrived in time to celebrate another family milestone: Travis' 48th birthday.
On Nov. 14, Kourtney penned a heartfelt tribute to the man she called "my husband, my soulmate, my best friend, my lover, my daddy to our baby boy, my everything."
"I wish you the happiest birthday," she wrote on Instagram alongside intimate photos of herself and the musician. "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."
Neither have publicly spoken out about their family's newest addition, though Travis had previously shared the meaning behind his son's unique moniker.
So, why Rocky Thirteen? "Rocky George played guitar for Suicidal Tendencies," he said during a July episode of Complex's "GOAT Talk" video series, explaining that the name also pays tribute to 1976's Rocky, which he described as "the greatest boxing movie of all time."
Travis, who has the numbers "1" and "13" tattooed on a skull near his elbow, added that he came up with the middle name Thirteen because it's "the greatest number of all time."

Months before she began dating Travis Barker, Kourtney Kardashian shared that she wanted to be pregnant again. When a follower asked if she was expecting, she responded, "No I wish." A few months later, she asked another fan on social media to "put the blessing out there."
The pair made their romance public soon after Valentine's Day.
Soon after getting engaged in October, they expressed interest in having a baby together and were hoping to be expecting by 2022, a source told E! News.
"They would love nothing more than to have a baby together," the source shared at the time. "Kourtney has always wanted another baby and never felt like she was done. Now that she's with Travis, she wants it even more."
Travis had baby on the brain after they celebrated Halloween together—with Kourt dressing as Patricia Arquette's character, Alabama Whitman, from True Romance. He commented on a photo of her, "Our sons name would be Elvis."
The Poosh founder confirmed she and Travis were truly trying to get pregnant in a March 2022 teaser for The Kardashians' first season. "Travis and I want to have a baby," she said, as cameras captured them consulting medical professionals to start the in vitro fertilization (IVF) process.
Kourtney told Access Hollywood just how many little rockers she wants with Travis, gushing, "I would love two, in a dream world."
Kim Kardashian reflected on Kravis' hope to grow their family, telling Ellen DeGeneres, "I think when you find love that you can't live without and there's still a chance—she's in her early 40s—I think they definitely want to see what life would be like with a baby."
In an April episode of The Kardashians, Kourtney said IVF has been "awful" for her. "It hasn't been the most amazing experience," she said. "The medication that they've been giving me, they put me into menopause."
She told mom Kris Jenner that online comments speculating about her pregnancy really affect her. "Every single person on social media is always like, 'Kourtney's pregnant,'" she said. "'Kourtney's gained so much weight.' And I'm like, it's so rude to comment on people when you have no idea what they're actually going through."
It's amore! Their families traveled from their home in Calabasas, Calif. to watch the couple get married in Italy.
The rocker duo shared that they were no longer going through the IVF process.
"We started an IVF journey, but I stopped," Kourtney told WSJ. Magazine at the time. "It was a lot. I took a break to just focus on our wedding and getting married."
Kourtney explained why parenting with the Blink-182 drummer just works so well, as she shares Mason, Penelope and Reign Disick with ex Scott Disick, while Travis shares Landon and Alabama Barker with ex Shanna Moakler and is also stepdad to Atiana De La Hoya.
"We have known each other and I have had my own relationship with his kids for, like, ten years," she told Today. "It does make it really easy. We all just know each other and each other's intentions."
She added, "I came from a blended family... We have experience."
When one fan commented, "Wait a minute, did I miss that she's pregnant?" on Kourtney's lingerie photo, the reality star replied, "Nope, but you're missing a woman's body."
Kourtney got candid on the negative effects of the fertility process, saying on the Not Skinny But Not Fat podcast, "It really took a toll on my health and mentally...The hormones. The medication. You have to get put to sleep every time. I know it's for so many people but it's just not for me."
As for why they tried it to begin with? "I felt like we kind of got pushed into doing IVF," she confessed. "If you look online, it says if you're over 40 go right away to an IVF doctor. So I felt a little bit pushed."
Kourtney's new philosophy is that the "timing" will work out on its own: "I feel like if it's truly meant to be it will happen."
When a social media user asked if she was expecting, Kourtney responded that her appearance has changed due to "the after affects of IVF [sic]." She clapped back by saying, "I only acknowledge this comment because I do think it's important to know how IVF affects women's bodies and it's not spoken about much. Also are we still asking women if they're pregnant?"
On a May episode of The Kardashians, Kourtney shared that the spouses were "officially done" with IVF, noting that her eggs "didn't survive the thaw" and that none of them "made it" to an embryo. "People do it thinking that it's like a safety net and it's not."
"We would love a baby more than anything, but I just really believe in what God has in store for us," she said in a confessional. "If that's a baby, then I believe that it will happen. Being happy is most important, and being a good parent to my kids."
They were still determined to grow their family and were trying on their own, she revealed in a May 2023 Hulu episode.
In fact, she told Khloe Kardashian that they were tracking her cycle. "I know that I'm already late for you, but I am ovulating," she shared. "If you give us five minutes to go do something really fast...we'll be back."
Fifteen minutes later, she was back and saying it was a "record."
The couple shared that they're expecting! Kourtney pulled off a romantic stunt at a Blink-182 concert in June 2023, holding up a sign saying, "Travis I'm Pregnant" like in their 1999 music video "All The Small Things."

The pregnant star shared she underwent urgent fetal surgery to save their son. "I will be forever grateful to my incredible doctors for saving our baby's life," Kourtney wrote on Instagram Sept. 6. "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."
