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:

  • Madonna

    Madonna's come a long way since telling David Letterman in 2009 that she'd <a href=",,20309345,00.html" target="_hplink">"rather get run over by a train"</a> than get married again. The Material Girl has previously been married to <a href=",,20097827,00.html" target="_hplink">Sean Penn</a> and <a href="" target="_hplink">director Guy Ritchie</a>, but in January 2012, she revealed to talk show host Graham Norton that <a href="" target="_hplink">she would consider becoming a wife for a third time</a>. "I could actually, yes," Madonna said. Maybe Madge's change of heart has something to do with her much younger boyfriend, <a href="" target="_hplink">French dancer Brahim Zaibat</a>?

  • Kim Kardashian

    Kim Kardashian hasn't let her two failed marriages -- the first to <a href=",,,00.html" target="_hplink">music producer Damon Thomas</a>, the second to NBA player <a href="" target="_hplink">Kris Humphries</a> -- shake her belief in love. "I still believe in love," <a href="" target="_hplink">Kardashian told Jay Leno in March 2012</a> after her October 2011 split from Humphries. "I'm in love with love. I thought this was it for me."

  • Jerry Lee Lewis

    Rock n' roll legend Jerry Lee Lewis has been married seven times, including one <a href="" target="_hplink">controversial marriage to his 13-year-old first cousin</a>. In 1986, the rock 'n roller gave a little insight into why he married so often when his sixth wife, <a href=",1850324&dq=would-marry-again&hl=en" target="_hplink">Kerrie Lynn McCarver Lewis, filed to divorce him</a>. (Though McCarver Lewis had a change of heart about the split, the pair ended up going through with the <a href="" target="_hplink">divorce in 2005</a>.) Asked if he would marry again, <a href=",1850324&dq=would-marry-again&hl=en" target="_hplink">Lewis told reporters</a>, "I said I wouldn't every time. But I don't believe in living in sin. I might get married again." Lewis made good on his word. In March 2012, the 76-year-old legend <a href="" target="_hplink">married his caregiver, Judith Brown,</a> in Mississippi.

  • Britney Spears

    Maybe the third time will be the charm for Britney Spears? The pop star's first marriage, to hometown friend, Jason Alexander, was <a href="" target="_hplink">annulled after just 55 hours in January 2004</a>, while her marriage to back-up dancer <a href=",,1556563,00.html" target="_hplink">Kevin Federline ended in November 2007</a> after two years of marriage and two children together. But in May 2011, <a href="" target="_hplink">Spears told <em>Harper's Bazaar</em> that she was open to marrying again</a> and having more children "if the timing was right." It didn't take long. In December 2011, Spears and longtime boyfriend and former manager <a href="" target="_hplink">Jason Trawick revealed that they were engaged</a>.

  • David Hasselhoff

    The Hoff just won't give up on love. After divorcing first wife, <a href="" target="_hplink">Catherine Hickland, in 1989</a>, David Hasslehoff <a href="" target="_hplink">found love with Pamela Bach</a>, the mother of his two daughters, Taylor Ann and Hayley. The <a href="" target="_hplink">couple divorced in July 2006</a> after 16 years of marriage -- but don't think the two failed attempts at marriage have soured Hasselhoff on love. "I want to be in love. I always try to make it last. I tried (for) 16 years to make my last marriage work but it's up to God, it really is... If you are meant to be together it will work," <a href="" target="_hplink">the actor told Britain's Sunday Express in April 2011</a>. "I would get married again though, sure. I love marriage. I felt guilty my marriages did not work."

  • Joan Crawford

    After three failed marriages, screen legend Joan Crawford admitted to reporters in 1952 that <a href=",59938&dq=would-marry+again&hl=en" target="_hplink">she would give marriage another shot</a> -- if only she could find the right man. "Certainly, I'd like to marry again," <a href=",59938&dq=would-marry+again&hl=en" target="_hplink">she said</a>, "I think every woman should be married to have a full, rich life. But I don't know anyone to marry." In 1955, Crawford married Alfred Steele, <a href="" target="_hplink">president of the board of Pepsi-Cola</a>.
