George Clooney's "biggest problem" is his daughter Ella.
The "Tender Bar" film-maker admitted his 4-year-old son Alexander is "easy" to please and keep entertained, but there are always dramas with the youngster's twin sister that require his and wife Amal's full attention.
Speaking to Daily Mail newspaper columnist Baz Bamigboye, he said: "Here's my biggest problem in life. That's my daughter Ella.
"Boys at this age are easy. Give them a stick and they start banging on things. They're fine.
"Ella woke up this morning with a sad face. I said, 'Are you okay, Ella?' It turns out that her doll was missing a shoe. It was a very tragic morning for us and believe me, all you want in life is to find that shoe."
