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.

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."
