Kourtney Kardashian, Travis Barker have wedding ceremony in Las Vegas after drummer's Grammy performance

Kourtney Kardashian and Travis Barker have officially walked down the aisle.

The "Keeping Up With the Kardashians" star and the Blink-182 drummer  had a wedding ceremony shortly after Barker's Grammy performance Sunday night in Las Vegas.

Marty Frierson, the owner of One Love Wedding Chapel, told USA TODAY that the couple's ceremony took place  at 1:45 a.m. Monday morning.

Prior to arriving, Kardashian and Barker called the chapel at 12:30 a.m. to confirm the 24-hour wedding chapel was still open for appointments.

Frierson was not allowed to take photos or videos of the ceremony but noted that Kardashian and Barker's four guests documented the ceremony on their phones.

While the couple's early-morning ceremony was the real deal, it's not clear whether the two are legally married.

Frierson added that it was not disclosed whether Kardashian and Barker obtained a marriage license ahead of the whirlwind ceremony.
