"She's an amazing human being," he told ET's Nancy O'Dell in May. "And she's caring. And she also happens to be one of the smartest people I've ever met. And she's got a great sense of humor."

The actor also noted Amal's amazing trend-setting fashion sense, which was on full display during their most recent outing with a sheer, coral dress that showed off her legs.
"She's always -- 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, and she was teaching at Columbia, and she's still like, 'I want to wear that dress.' It's crazy. It has been sort of fascinating to watch, because she has such great taste."
