One day after tying the knot with Ben Affleck in a late-night wedding ceremony in Las Vegas on Saturday,

Jennifer Lopez confirmed the news on Instagram with a photo from bed.

In a newsletter to her fans, Lopez, 52, detailed their intimate wedding, which she called "the best night ever."

Lopez, who indicated that she plans to use Affleck's last name in a Clark

County marriage license obtained by PEOPLE, signed her newsletter with "Mrs. Jennifer Lynn Affleck."

The stars rekindled their relationship last year and have been fiercely

protective of their second chance at love. "We're older now, we're smarter, we have more experience,

we're at different places in our lives, we have kids now, and we have to be very conscious of those things,"
