"It’s what is in the heart."

Kourtney Kardashian has hit back at rumours that her Las Vegas wedding was fake. On Sunday night, Kourtney married her partner Travis Barker at a small chapel in the city, shortly after the pair appeared at the Grammys together. The reality TV star later shared some snaps from the ceremony with her fans, and confirmed that they didn’t have a marriage license on them, before describing that the ceremony as a "practice".

"Found these in my camera roll," she wrote on Instagram. "Once upon a time in a land far, far away (Las Vegas) at 2am, after an epic night and a little tequila, a queen and her handsome king ventured out to the only open chapel with an Elvis and got married (with no license). Practice makes perfect."

Many have accused her of staging the whole thing as a "publicity stunt" to promote her family's new show, which lands on Hulu next week. But appearing on The Jimmy Kimmel show on Wednesday night alongside her sisters, Kourtney shot down the rumours - saying it's how you really feel that matters and not a piece of paper. "Kourtney I think you’re the Kardashian of the week this week because you went ahead and got fake married," Jimmy said said to her. Quickly interrupting him, she responded:"Well it’s not called fake married. There was no possibility to get a marriage license at that hour." Kim then joked: "Isn’t everything 24/7?"

"That’s what I thought!" Kourtney said. "And I’m like, are you guys lying? We asked five times like, what do we have to do to make this happen?

"It was 2am and they were like, 'it opens at 8 o’clock'. So, we just did it anyway. It’s what is in the heart."

Kris then revealed that she knew all about the couple's plans to marry in Vegas, and Khloe said she even FaceTimed her sister during the ceremony. Earlier this week, sources told TMZ that this will not be Kourtney and Travis' only wedding, as they plan to have "several" ceremonies in the future with family, friends and “lots of fanfare".
