Amal Alamuddin and George Clooney, 6 months: After his divorce from Talia Balsam, Clooney swore he would never marry again. But his feelings changed when he met human rights lawyer Alamuddin in September 2013. Their official first date was that October, and six months later, the actor popped the question — though the proposal didn't go as smoothly as he hoped it would. "I got down on my knee and said, 'I couldn't imagine spending the rest of my life without you.' And she kept looking at the ring and she was looking at me and she was like, 'Oh my God,'" he recalled to Ellen DeGeneres. "And we now know, because there was a playlist, so we know how long it actually took, and it was like 25 minutes. Finally, I literally said, 'Look, I hope the answer's yes, but I need an answer 'cause I'm 52 and I could throw out my hip pretty soon.' And she said, 'Oh, yes,' and it worked out really well." The two married later that year and in June 2017 became parents to twins Ella and Alexander. (Photo via Jamie McCarthy/Getty Images)
