Travis Barker's eldest son has revealed that he is pushing his big brother duties to the side.
The 48-year-old Blink-182 drummer and his wife Kourtney Kardashian welcomed a baby boy named Rocky Thirteen on November 1.
The newborn is the 44-year-old reality TV star's fourth child as as she shares Mason, 13, Penelope, 11, and Reign, eight with ex-boyfriend Scott Disick, 40.
Meanwhile, Rocky is Travis's third child as he shares Landon, 20, and Alabama, 17, with his ex-wife Shanna Moakler, and also considers Shanna's daughter Atiana De La Hoya - whom she had with former boxer Oscar De La Hoya - as his child too.
The newest addition to the couple's blended family means they're spending quality time with the little one, however, the rock star's oldest son recently admitted that he is not involved in any of the day-to-day activities regarding his baby brother.
"Have you changed any diapers yet?", interviewer Jess Lucero asked Landon on SiriusXM TikTok Radio, to which he shockingly responded: "I have not. And I will not be."
In fact, the 'Friends With Your Ex' musician confessed that he hasn't even "held it," meaning his baby bro, and referenced a previous comment he made on the Zach Sang Show about wanting to be the "only Barker boy" in the family.
At the time, the singer said: "I kinda wish it was a girl though," and acknowledged that there would be an age gap between him and his brother. "We're almost 20 years apart. So I feel like our lives are gonna be very different. I'm sure he'll have, like, the iPhone f***in' 25," he said.
Watch Landon talk about his baby brother below:Landon's remarks about his baby brother on the radio show sparked lots of comments on the social media platform, with many sharing their reactions to him calling Rocky an "it".
One person said: "Referring to his brother as 'it' is wild."
A second interjected: "I wouldn't let him touch my child like you really called your little brother a 'it' like wtf."
A third user was in disbelief and wrote: "Bro the fact that he hasn’t even held the baby is CRAZY," while a fourth added: "It’s probably weird how big of an age difference. I’m 25 and my mom had a baby [with] my stepdad. it's like 2 different families."
Needless to say, getting a younger sibling is a totally new and "crazy" experience for Landon.
"I've never really had a baby sibling. It's always been me and my sister, two years apart," he explained at the time. "It's cool though because it'd be different if it happened when I kinda need the attention as a kid."
Meanwhile, Landon's younger sister Alabama told E! News that she was ready to welcome Rocky into their home sweet home. "I just think having another family member is always awesome," the teenager excitedly shared.
"And getting to know a new person, it's gonna be so fun and so exciting!", she added.
