Jennifer Lopez details the moment Ben Affleck proposed for a second time

"Just a quiet Saturday night at home."

Jennifer Lopez has opened up about the moment Ben Affleck proposed to her for a second time, sharing that while it was "nothing fancy" it was the "most romantic thing" she could've imagined. Some 18 years after calling off their previous engagement, the singer-actress, 52, revealed on Friday that the couple are again engaged. Ben, 49, had proposed with a green engagement ring. Now, Jennifer has revealed how it all went down in a new edition of her On the JLo newsletter. "Did you ever imagine your biggest dream could come true?" she began the newsletter. "Saturday night while at my favorite place on earth (in the bubble bath), my beautiful love got on one knee and proposed.

I said 'YES of course that's a YES.'" She continued: "I was smiling so big and tears were coming down my face, feeling so incredibly happy and whole. It was nothing fancy at all, but it was the most romantic thing I could've ever imagined... just a quiet Saturday night at home, two people promising to always be there for each other. "Two very lucky people. Who got a second chance at true love." Jennifer also explained the reason behind her engagement ring being green: "Green has always been my lucky colour and now, for sure, it always will be."

"There's more of an appreciation and a celebration for it, which is nice," she told People. "When you find somebody and you really, really love them and you get a second chance at that? That is a really rare, precious, beautiful thing and we don't take it for granted. "...What I can teach my children is that real love exists. Some things can be forever, but it doesn't mean they just have a straight line."
