In a video of the moment Kardashian shared to Instagram, the drummer leaves the stage to give her a celebratory kiss.

On Sept. 1, Blink-182 postponed the band's European tour dates due to an "urgent family matter" for Barker. Nearly a week later, on Sept. 6, Kardashian revealed on Instagram that she underwent "urgent fetal surgery" to save their baby.

In her post, Kardashian said she had "a whole new understanding and respect for mamas who have had to fight for their babies while pregnant," adding, "Praise be to God. Walking out of the hospital with my baby boy in my tummy and safe was the truest blessing."

In an interview with Vogue on Oct. 17, Kardashian credited an ultrasound for catching the issue with her baby that required surgery, saying, "That experience opened my eyes to a whole new world of pregnancy that I didn't know about in the past."

"It was terrifying," she said of the experience. "After, I learned that insurance typically only covers two ultrasounds when you're pregnant, I had no idea. I've always been lucky enough to do more than what insurance covers, and it's one of those ultrasounds that saved my baby's life."
