London: `Dance Again` singer Jennifer Lopez is unsure if marriage is on the cards ever again for her even though she is in a long-term relationship with back-up dancer Casper Smart.
The 44-year-old says that despite all the challenges she faced in her previous relationships, she believes in love, reported Contactmusic.
"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," she said.
When asked if wedding bells are in her future, she replied, "I don`t know, we`ll see. I don`t know."
Lopez thinks Casper Smart is "fantastic" with her children but the singer still isn`t sure if a fourth marriage will ever happen.
"I don`t like the word father figure, but he`s fantastic with the kids and he helps me very much with my work," she said.
