Clooney has been stepping out in the most gorgeous ensembles in the past months. Earlier this month, she turned heads in a lilac Versace Atelier gown at the Venice Film Festival and wowed in a shimmering royal blue Missoni dress while out to dinner with friends.
ET recently caught up with the human rights lawyer's movie star husband about his newborns and their personalities.

The 56-year-old actor also praised Amal for already being an amazing mother. See what he had to say in the video below.
