George Clooney Can't Stop Gushing About Wife Amal

"There's a number of reasons why" George Clooney says.

"She's an amazing human being and she's caring," he told "Entertainment Tonight". "And she also happens to be one of the smartest people I've ever met. And she's got a great sense of humor. There's a number of reasons why [I fell in love]."

But the "Tomorrowland" star didn't forget to bring up his wife's well-known sense of high fashion.

"Since the day I met her -- she's always had this insanely ... it's eccentric but it's fun, sense of fashion," he said. "How she does it while she's got 11 cases she's working on? ... It's crazy. It has been sort of fascinating to watch, because she has such great taste.”
