NRL star Cooper Johns and his girlfriend Kenna Hullick return to Sydney after he did things he wasn’t “proud” of during a wild trip to Las Vegas.

Cooper Johns and his girlfriend Kenna Hullick landed at Sydney Airport on Tuesday after their wild trip to Las Vegas.

The recently retired NRL star, 24, had flown to Sin City with his girlfriend Kenna to work for KIIS FM ahead of Sunday’s NRL double-header at Allegiant Stadium.

He was left truly partying after the jam-packed five-day trip and was told he wasn’t “very proud” of some of his behaviour.

Landing in Sydney after the shindig, Cooper cut a relaxed figure in black tracksuit bottoms and a gray jumper, which he teamed with a cream cap.

His girlfriend Kenna also cut a sporty figure in black sweatpants and a white and pink Mickey Mouse sweater, along with blue sneakers and a black cap.

The couple looked ready to get home after the 15-hour flight and wild week in Los Angeles as they carried their suitcases outside the airport and waited for their car.

It comes after Cooper gave insight into his trip to Los Angeles, telling KIIS FM’s Kyle Sandilands and Jackie ‘O’ Henderson that he will never return to the party city.

“I’m so sick of Las Vegas that I hope I never have to come back here again,” he said.

He confessed that he wasn’t “very proud” of some of his behavior as he enjoyed a night out after seeing rapper Ludicrous perform on Saturday night.

“There are some things I did that I wish I could take back that I’m not very proud of,” he said.

Cooper recalled that at one point, he was walking through the casino in the early hours of the morning “very drunk.”

“That’s the beauty of Las Vegas, you can basically do whatever you want and there are no consequences for it,” he added.

The former Manly Sea Eagles player also told the hosts how Kenna lost his passport in the US city after using it as a form of identification.

After a phone call with the Australian embassy, ​​the couple eventually found the passport in Johns’ former teammate’s room.

Speaking from the airport before his flight back to Sydney, Cooper said he recommended making the trip just once in your life.

“Everyone should probably do it once in their life, but not for five nights,” he said.

The former five-eighth resigned from the NRL earlier this year following spells with the Melbourne Storm and Manly Sea Eagles dating back to 2020, and is now working with KIIS FM as an on-air talent.
