Kourtney Kardashian and boyfriend Travis Barker have date night at UFC 260

Kourtney Kardashian and boyfriend Travis Barker have taken their romance to Sin City.

On Saturday, the couple attended the star-studded UFC 260 event at UFC APEX in Las Vegas, where Francis Ngannou knocked out Stipe Miocic to secure the heavyweight title.

Both sporting black jackets, Kardashian, 41, and Barker, 45, sat beside one another at the venue, where Megan Fox and boyfriend Machine Gun Kelly were also in attendance.

Following the fight, we’re told both couples headed to Barbershop Cuts and Cocktails at The Cosmopolitan resort.

First linked in January, Kardashian and Barker made their relationship Instagram-official a month later. The “Keeping Up with the Kardashians” personality posted a photo of the couple’s hands intertwined. The Blink-182 rocker replied to the post with a black heart emoji.

The pair also spent Valentine’s Day together.

This month, Barker shared an “I love you” note from Kardashian, who was recently photographed wearing a risqué T-shirt during a date night in Malibu.

Last week, Barker had fans speculating that his new tattoo was a permanent tribute to Kardashian. The drummer had “You’re So Cool!” — the title of a Hans Zimmer song from the 1993 film “True Romance” — tattooed on his thigh.

“Kourtney wrote that, huh,” one fan responded.

Prior to her romance with Barker, Kardashian dated Algerian model Younes Bendjima. Kardashian’s younger sister, Khloé Kardashian, previously called him “toxic.”

Kardashian and former beau Scott Disick also have three children together: sons Mason, 11, Reign, 6, and 8-year-old daughter Penelope.

As for Barker, he was previously married to Melissa Kennedy from 2001 to 2002. He was later married to Shanna Moakler from 2004 to 2008. They share two children: daughter Alabama, 15, and son Landon, 17.
