ENTERTAINMENT NEWS - Clooney previously admitted he "didn't think" he would be a dad with twins at 56.
George Clooney has admitted fatherhood has made him feel "much older" but praised the "all-new adventure" ahead for him.
The Hail, Caesar!' star welcomed his first children, twins Ella and Alexander, into the world back in June and he admits becoming a dad is an "all-new adventure" for him.
Speaking to Entertainment Tonight, he said: "Its true. He's got me. I'm a mess. But [Amal] is like an Olympic athlete. You've got two kids, you're breastfeeding like crazy. I'm very good, by the way, at diaper changing. This is an all-new adventure for me, but I've been through it with all my friends, so it's not really that much of a surprise.
"[Fatherhood] has made me much older. It doesn't fundamentally change you, but I'm excited to see who these two people are going to be in life. I'm very proud to be [a dad]. I feel honoured to be a part of it."
Meanwhile, Clooney previously admitted he "didn't think" he would be a dad with twins at 56.
He shared: "Suddenly, you're responsible for other people, which is terrifying. Amal's like an Olympic athlete. She's doing so beautifully.
"Right now my job is changing diapers and walking them around a little bit. I really didn't think at 56 that I would be the parent of twins. Don't make plans. You always have to just enjoy the ride."
