Jennifer Lopez unsure if she'll marry again

Jennifer Lopez is three times married, and recently again divorced.

And though she is happily in a relationship Casper Smart, her former backup dancer, Lopez says she isn't sure if she'll head down the aisle a fourth time.

"I don't know. We'll see. I don't know," she said. "You know, I've always believed in that institution. I believe in it, but it is difficult. I've had my challenges, but at the same time I believe in love, and I think that is the main thing."

Still, being married three times (most recently to Marc Anthony, who filed for divorce in April 2012), has taught Lopez a lot about herself.

"I'm one of those people who does not like to be alone," the American Idol judge said. "I have no shame saying that at this point in my life. I think we have to own who we are."

Lopez, who has 5-year-old twins Emme and Max with Anthony, said Smart is "fantastic" with them, and she relied heavily on him and her mother when she went on her first world tour last year.

"That was such a transformative year for me in so many ways," Lopez said. "I had just divorced, I went on tour with the kids, and I left Idol. All my security blankets were gone, and I was out there doing something I had never done before."
