Reality TV star Kourtney Kardashian and Blink-182 drummer Travis Barker got married at a wedding chapel in Las Vegas after the Grammy Awards-but the union isn't actually legal.

Kardashian, 42, and Barker, 46, made the quick decision early Monday around 1:30 a.m. Pacific, only a few hours after the awards ended Sunday night. However, on Tuesday, the marriage was revealed to not be legal since the couple did not obtain a marriage license before the ceremony.

"In Nevada, a couple would be allowed to get married in Las Vegas with a marriage license that was issued by another Nevada county," The Clark County Office of Public Communications said in a statement. "In that scenario, the marriage certificate would be filed with the county that issued the license. Also, in Nevada a couple must have a marriage license before they get married."

Clark County confirmed they had not issued a license to the couple as of 8 a.m. Tuesday.

One Love Wedding Chapel owner Marty Frierson confirmed that the couple did get married at the chapel in an interview with Fox News Digital on Tuesday. The two announced their engagement in October.

"Yes, they got married after the awards show at 1:45 a.m. at my chapel, One Love Wedding Chapel. They called about 12:30 a.m.," Frierson said.

Frierson also shared that the couple “requested an Elvis Presley impersonator to wed them” and that he was able to accommodate them. "My chapel is 24 hours, and they wanted to make sure I can get Elvis Presley. I wasn't sure if I could get Elvis, I said let me check and I got the Elvis, they paid online, and they came in and got married."

No pictures of the wedding have been released yet, as Kardashian and Barker requested to have their own photographer and security present. It was reported that the couple was wearing the same clothes that they were wearing during the awards show.

A source told TMZ that the two will have another ceremony to celebrate their marriage, along with “several” other celebrations.
