The 51-year-old supermodel and her husband Rande Gerber are thrilled their close pals are expecting twins and think it is a "natural next step" for the couple.

She said: "I'm very excited. Obviously, we're friends of parenthood. I think it's incredible for George and it really took Amal, I think. She's just so amazing and they're just so happy. It just seemed like a natural next step."

However, Randy joked his close friend and business partner wouldn't be the one changing diapers.

He said: "I'm not sure he'll be changing diapers."

Whilst Cindy quipped back: "By the way, you don't know how to do diapers."

And Cindy - who has Kaia, 15, and Presley, 17, with Rande - recalled how she knew Amal was the one for George when he first introduced her to them.

She told E! News: "It was like all of a sudden he might get married and he might have a family. It's incredible. We are very excited for them."

Meanwhile, George previously revealed the couple have "decided to be much more responsible" after finding out they are expecting twins.

He said: "We decided to be much more responsible, to avoid the danger. I will not go to South Sudan anymore and in the Congo, Amal will no longer go to Iraq and she will avoid places where she knows she is not welcome.

"Before, I did not care, I would even say that there was a pretty exciting side to going where no reporter had ever been. We have the chance to live between three countries: Italy, America and England."

And the pair will choose somewhere to settle once their twins reach school age.

He added: "[When they go to school, we'll] choose where to settle. In the meantime, we will continue to move according to our respective schedules. People think we're never together, but we have not been separated for more than a week."

And George previously described how he thinks parenthood will "be an adventure".

He said: "We are really happy and really excited. It's going to be an adventure. We've sort of embraced it all with arms wide open."
