George Clooney has gushed about his wife Amal Alamuddin, saying she is an "amazing human being".

The actor and director married the human rights lawyer last September in a lavish ceremony in Venice, and eight months after their nuptials it appears their marriage is going terrifically.

He told Entertainment Tonight: "She's an amazing human being. 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 humour."

However, Clooney did admit that one of his habits does annoy her, saying: "I watch sports and it kills her because I got her into March Madness a little. She got into that, but it was enough, so the next week was the Masters, and I'm watching that and she goes, 'So every weekend we're going to be watching a sporting event.' I'm like, 'Actually, that's how it works.'"
