The duo pronounced their separation in 2011 after seven years together, and Anthony filed for divorce in 2012, with the union officially dissolved last June (14).

In the show, which premiered in the U.S. on Wednesday (31Dec14), Lopez said, "I remember being on the set and being in my dressing room and not feeling like I could get up in the morning and there's just no pain like that. There's no pain or failure like going through a divorce... That hope, that dream, that fairytale, with that first time that dream gets blown to pieces, and you feel like you're going to die... You feel like you failed. You feel like no matter how hard I tried, I couldn't make it work."
