Jennifer Lopez's new single 'Wreckage of You' is a raw unfurling of her breakup with Ben Affleck. Here's everything we know.

During her first show in her Up All Night tour, which got started yesterday on July 8 in Vigo, Spain, Lopez debuted an emotional new ballad. “This is a new song that I’m gonna sing for the first time tonight that came to me when I was up all night one night,” Lopez said in a video posted by a fan in the audience.
