The 'On the Floor' singer separated from Anthony in July 2011 after seven years together.
In an interview with USA Today, Lopez said that her "whole world fell apart" when her marriage ended.
"I felt in [a] low place. It was the worst time in my life," she recalled. "[My kids Emme and Max] didn't know anything. They're starting to figure it out now, a year and a half later. They were just 3 at the time."
Lopez has since moved on to dating dancer Casper Smart, with engagement rumours popping up in the press in recent months.
"He's a nice person. My life is really good right now," the star said of Smart. "I'm at a point where I'm able to make decisions based on what I really want to do.
"I'm making decisions based on what I feel, which is never wrong no matter what the outcome is."
Lopez recently insisted that she has no regrets about her failed relationships with Marc Anthony, P Diddy and Ben Affleck.
Her new crime thriller Parker - which also stars Jason Statham - is now playing in the US and opens on March 8 in the UK. Watch a trailer below:
