The couple later celebrated with Travis' daughter Alabama, 16. Barker's other kids — son Landon, 18, and stepdaughter Atiana, 23, whom Moakler shares with boxer Oscar De La Hoya — did not appear to be in attendance for the wedding.

The newlyweds also shared several photos from their Santa Barbara nuptials on Instagram, including the couple walking hand-in-hand down the stairs of the courthouse, kissing in their convertible and posing in front of the car. Barker's post also featured a photo of the newlyweds getting intimate on the hood of their vehicle.

The couple opted for matching captions that read, "Till death do us part."

In April, the pair had a "practice wedding" complete with an Elvis Presley impersonator, who officiated the ceremony, in Las Vegas following the 2022 Grammys. Kardashian later confirmed that they didn't have a marriage license for the intimate affair.

Kardashian and Barker got engaged in October 2021 on the beach in Montecito, California. The pair had been dating for less than a year when the rocker got down on one knee. The moment was captured for The Kardashians on Hulu, and the celebration continued after with a surprise dinner for both their families.
