The 57-year-old Hollywood legend joked that he missed out on the first night of his Casamigos party because he was busy at home changing his and wife Amal's 16-month-old babies' diapers.

Speaking at the second bash at the Aria Resort & Casino in Las Vegas on Sunday night (28.10.18), where he and his business partner Rande Gerber dressed as pilots, he laughed: "Last night they were dressed up as rockstars, and I was dressed up as a guy cleaning crap out of a baby's diaper.

"It was a fantastic costume. Oh, so much fun, you could imagine the fun I had last night."

Rande's wife Cindy Crawford joined in the fun by donning an air hostess outfit, and captioned a picture of the three of them on Instagram: "Now boarding: @Casamigos Air #casamigoshalloween (sic)"

Speaking about their costume choices, the 52-year-old star told 'Entertainment Tonight': "You don't want to do the same thing two nights in a row. Last night we kinda had a thing going with our kids and then tonight we are flying to Vegas, and it was like, I guess the whole flight thing."

Whilst Rande, 56, and the 'Money Monster' star quipped about how much Tequila was consumed at the party.

He said: "I have a pretty good liver, you?", to which his George replied: "Getting a new one next week."

The 'Gravity' actor also admitted that his costumes will be less "terrible" now he's a father and in his 50s.

He said: "Oh, I've done some terrible costumes.

"I went as a milk carton with my face sticking out the side that said 'Have you seen this child lately?'

"That was a bad one.

"I've done some terrible ones, but that was 30 years ago. I can't be held responsible for that."

Last year, George and Rande's 70s-themed night on the Sunset Strip was attended by the likes of Kim Kardashian West and Sylvester Stallone.

The pair decided to sell their stake in the firm last year to the alcoholic beverage company Diageo, which agreed to pay $700 million to assume control of the brand, with the potential for another $300 million based on its performance over the next decade.
