Rande Gerber, Clooney's close friend and an entertainment industry businessman, revealed to MSNBC's Headliners how Clooney called him and 13 other friends, the group known as 'The Boys', for a dinner in 2013 to give them the surprise.

"George had called me and The Boys and said 'Hey, mark 27 September, 2013, on your calendar. Everyone's going to come to my house for dinner', " said Gerber, who is married to model Cindy Crawford.

He recalled when the group arrived at the actor's house, each of them found a black designer suitcase at their places at the table.

Gerber further revealed: "George begins to say 'Listen, I want you guys to know how much you've meant to me and how much you mean to me in my life.

"I came to L.A., I slept on your couch. I'm so fortunate in my life to have all of you and I couldn't be where I am today without all of you'. "

And, they left in shock later when they opened the suitcases, each found $1 million (around £750,000) in $20 notes.

"Every single one of us. We're in shock. Like 'What is this?' "

But the Up in the Air actor went on to explain how he wants them not to worry about their kids, the hard time they were going through.

"He goes 'I know we've all been through some hard times, some of you are still going through it. You don't have to worry about your kids, you don't have to worry about, you know, school, you don't have to worry about paying your mortgage'. "

This is not the only thing. He even paid off their taxes that year.

Gerber also said that he was being a bit hesitant about it, then Clooney said, "If Rande doesn't take the million dollars, nobody gets it."

One among 'The Boys' was working at a bar in Texas and used to ride a bicycle to work every day as he was putting so much effort just to support his family.

Crawford's husband also noted a coincidence about the date September 27 — the actor gave it back to his friends in 2013 on that date and in 2014, he tied the knot with Amal Clooney on the same date.

According to The Sunday Times, the joint wealth of the Hollywood actor and his wife was worth $121 million in 2015.
