London - He is the smoothie Hollywood star and she is the stunning British human rights lawyer. 

Together George and Amal Clooney make a glamorous pair and my, aren’t they keen to tell us how crazy they are for each other?

The Swoony Clooneys put on quite a show at the American Film Institute awards last week where she revealed she had resigned herself to being a spinster before she found "the great love I always hoped existed". So just how lovestruck are they?

Amal, then 35, first met George, then 52, just five years ago when she went with a friend to a party at his house on Lake Como, in Italy, and they stayed in touch.

George said: "I knew when I met her that she was super-extraordinary. I wondered if I would ever get a chance to date her. We were friends for a while and luckily she said yes."

"Amal is a big emailer," Vogue magazine revealed, describing how romance grew, "and George responded with a clownish gambit, writing her notes, supposed to be from of his dog Einstein, claiming to be trapped in various places and in need of legal rescue."

In an interview with the Hollywood Reporter George confirmed the story, saying that the dog, a cocker spaniel, claimed he was being held hostage.

The dog has since died but is immortalised in a painting which sits on their  mantelpiece.

He is "dressed as a physics professor" and standing in front of a blackboard.

Their next meeting was at the Abbey Road studios in London - where George was recording a film soundtrack and invited her along. He had hoped the venue would make him seem cool, and was deflated when Amal said she had just been visiting the Muslim Brotherhood while he was trying to impress her with a "dumb movie score".

"I met George when I was 35 and starting to become quite resigned to the idea that I was going to be a spinster." Amal told the American Film Institute on Thursday.

"Then we met and started hiding out in my London flat and very soon it felt like, no matter what happened, I would never want to be with anyone else. He is the person who has my complete admiration and also the person whose smile makes me melt every time. My love, what I have found with you is the great love I always hoped existed and seeing you with our children Ella and Alexander is the greatest joy in my life."

George is even more complimentary. He told an interviewer: "Look, it’s good to surround yourself with anybody who is smarter than you, and for me the bar’s pretty low anyway. But Amal is way up there. She’s brilliant."

Accepting an award at the 2015 Golden Globes, George oozed: "Amal, whatever alchemy it is that brought us together, I couldn’t be more proud to be your husband."

A visit to Kenya together in February 2014 sealed their love. "Amal loves giraffes; they’re her favourite animal," said George. "She went to this place called Giraffe Manor, where the giraffes stick their heads through the windows and kiss you." Back in LA, he showed a photo to his actor friend Ben Weiss.

"I had a picture of her, looking back, smiling at these giraffes, and I said: 'I think I’m going to ask her to marry me.' And Ben said: 'I think that’s a good idea.' "

For Clooney - previously married to actress Talia Balsam - it was quite a step, having spent decades dating cocktail waitresses, party girls and even a professional wrestler.

He told Vogue: "If you know anything about my crazy life, you know that I’d pretty much committed to the idea of never marrying again, but I started dating Amal, and I immediately knew that something was very different."
