'On The Floor' beauty Jennifer Lopez has spoken out in praise of her 25-year-old boyfriend and described him as her closest loved one.

The pair have been in a relationship for some time and 43-year-old Lopez told the February edition of Harper's Bazaar magazine that Casper Smart has been there with her through everything and she couldn't wish for a better partner:

"He's fantastic; he's like my best friend. I can tell him everything, when I'm feeling down, when I'm feeling good. He gives moral support, endless love and support."

Lopez added that while she isn't at her best when she's tired, she enjoys her busy schedule and wouldn't change anything if she had the chance:

"The worst is when I'm tired. It's the overworking, which I've learned to say no to. I'm not my best self. I'm at my best, I think, when I'm giving love. I feel my best, I am my best, I need my best."

"I'm a singer. I'm a dancer. I'm a performer. I'm an actress. That's what I'm supposed to be doing. It makes me a better parent, a better person. I think I can just handle more than the average bear, you know? I make it as simple and as beautiful as I can because my life is kind of big. So I pack my luggage, or dress myself, or comb my kids' hair, pick up their clothes--that makes our life beautiful, you know? There's something very elegant in that."
