Jennifer Lopez and Casper Smart

Jennifer Lopez and Casper Smart, Jennifer Lopez stopped by "Katie" on Friday to chat about her recent divorce and 25-year-old boyfriend, Casper Smart. Lopez, 43, dished on her and Smart's 18-year age difference with host Katie Couric, who also famously dated a much younger man -- Brooks Perlin, who is 17 years Couric's junior. "It’s hard for me to think of my age," Lopez said. "I feel very youthful. And I feel very comfortable in my own skin. And it’s funny, until somebody brings it up, I don’t think we really think about it." The former "American Idol" judge revealed that she feels "lucky" that Smart -- who is also her backup dancer and choreographer -- came into her life. "We’re enjoying each other’s company and he’s a great support system and he’s great at what he does," she said. Rumors of their relationship surfaced in November 2011 when Smart was spotted leaving Lopez's New York City hotel. The pair broke their silence about the relationship in a July 2012 interview on "Good Morning America." Lopez also opened up to Couric about her divorce from estranged husband Marc Anthony, whom she split from in July 2011. It was really tough decision to make, and one that in your heart, is always just going to affect you," she said. "You never want to break up a family. That wasn’t my dream. My dream was for us to always be together. But things don’t work out and you feel like it’s the better choice. If I didn’t feel it was the better choice then I wouldn’t have done it. But we’re doing good with it." Despite Lopez's three failed attempts at marriage, the songstress has said that she would walk down the aisle again. She's not the only celeb to still believe in love, having experienced divorce. Click through the slideshow below for six others:
