Kourtney Kardashian is taking a sweet trip down memory lane.
In honor of her stepson Landon Barker's 20th birthday, the Kardashians star—who wed Travis Barker in 2022—posted a few snapshots of the "Friends With Your EX" musician, including one throwback photo dating back to way before she and Travis became a couple.
In the pic shared to her Instagram Stories Oct. 9, a younger Landon is seen making a peace sign alongside Kourtney's oldest son Mason Disick, now 13, captioning her post, "how is this 2017."
And that's not all, as the Poosh founder—who shares kids Mason, Penelope, 11, and Reign, 8, with ex Scott Disick—also posted a TikTok of her and Landon, along with the caption, "HAPPY BIRTHDAY @landonasherbarker I can't believe you're 20!"
Kourtney—who is pregnant with her and Travis' first baby together—also followed up their TikTok with another photo of her, Travis and Landon at Coachella. Alongside the photo of the trio, she added an arrow pointing toward her stomach, writing, "baby Barker."
As for Travis himself? The rocker—who is dad to Landon, Alabama, 17, and stepdad to Atiana De La Hoya, 24, with ex Shanna Moakler—shared a special shoutout to his "mini me."
"Happy Birthday to the most amazing son I could ever ask for," he captioned his Instagram post featuring a series of throwback photos of Landon. "I can't believe you're 20! The day you were born you made me a better person and you have filled my life with so much happiness. I'm so proud of the man you have become and I love you."
