Just when you thought Leonardo DiCaprio couldn't get any more attractive, he goes and takes a selfie that might just make you turn into mush on the spot. While serving as a UN Messenger of Peace during the Paris Agreement to talk about climate change on Friday, the actor took a moment to show off his gorgeous eyes by snapping a sweet picture of himself. The United Nations shared it on Twitter, writing, "@LeoDiCaprio takes his UN Messenger of Peace duties seriously! Thanks for the #ParisAgreement support!" While he definitely looks super handsome, we have to admit, nothing can quite top this throwback photo of him with Britney Spears. See the glorious selfie above, then check out some of his most attractive moments over the years.
