The inseparable pair, known to fans as "Kravis," tied the knot in Las Vegas early Monday after attending the Grammy Awards, according to multiple news outlets, including People and TMZ. However, it's unclear if they obtained a marriage license before the ceremony.

The lovebirds — whose romance will play big into the new Hulu show The Kardashians, which premieres April 14 — showed up at the One Love Wedding Chapel at 1:45 a.m. on Monday morning with security in tow. Hours earlier, Barker performed at the Grammys.

They paid in advance and requested that owner Marty Frierson secure an Elvis impersonator to officiate. When they showed up, they brought their own photographer and didn't allow the venue to photograph them. The ceremony lasted about 30 minutes.

There now seems to be a discrepancy over whether this is a legal marriage. TMZ initially reported that they arrived with a marriage license — and the venue's website notes one must be obtained prior to the ceremony. However, the outlet now says the couple "hadn't gotten a license and only did it for fun."

Yahoo Entertainment has reached out to Kourtney's rep as well as chapel owner Frierson and we will update this story when we hear back.

Frierson did speak to People magazine before the validity of the marriage was in question to share details about the unexpected bride and groom.

"I didn't know who it was until they pulled up," Frierson said. "I advertise as 24-hours but they wanted to make sure I was still there. They paid and they requested Elvis Presley, that was mandatory. I called back 5 minutes later and was like, I got an Elvis, and there they were."

He added, "They came, got married, tossed the bouquet in the driveway, and danced to Elvis. They showed a lot [of] love and had a lot of fun."
This is reportedly one of several weddings for the pair. Expect them all to air on Hulu.

On Sunday night, the pair attended the Grammys together in Vegas, touching tongues on the red carpet — and making out during the show.

The PDA-loving pair were friends for years before they started dating in December 2020. (Barker actually had a long-ago fling with Kim Kardashian, if the gossip is true.) Kravis made their relationship Instagram official in February 2021.

Kourtney, 42, and Barker, 46, became engaged in October at the Rosewood Miramar hotel in Montecito, Calif., celebrating with family — including momager Kris and her famous sisters — after.

Kourtney, who helped Barker overcome his fear of flying, has shared that they've been undergoing IVF to try to get pregnant.

This is Kourtney's first marriage, though she shares three children — Mason, 12, Penelope, 9 and Reign, 7 — with ex Scott Disick (who isn't a huge fan of the coupling).

The drummer was previously married twice and has two children — Alabama, 16, and Landon, 18, — from his second marriage to Shanna Moakler (who's also not a superfan of the coupling). He is also stepdad to Moakler's daughter Atiana De La Hoya.
