When asked about marriage for the fourth time, the mum-of-two admitted she was unsure but said that she still believed in it.
The 44-year-old said: “I don’t know. We’ll see. You know, I’ve always believed in that institution. I believe in it, but it’s difficult.
“I’ve had my challenges, but at the same time I believe in love, and I think that is the main thing.”

The singer, who was promoting the 13th season of American Idol, also revealed that she has come to terms with the fact that she needs to be in a relationship.
She said: “I’m one of those people who does not like to be alone. I have no shame in saying that at this point in my life. I think we have to own who we are.”
Jennifer, who is still yet to finalise her divorce from last husband Marc Anthony, spoke about how going on tour last year helped her to get over the break-up.
She 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.
“I was surrounded by love and family. I really grew. My goal was not to come out of the other side and just survive it but to grow as a human being as well as an artist, and I felt I did. I learned a lot.”
