Jennifer Lopez says motherhood is the most important thing to her

She told MTV: "Mommy. It's just the one thing you don't want to mess up. You can mess up in all other areas and get back up, but you don't want to mess up there.

They're so precious to you, and they make everything better in my life. They make me feel better every single day. Definitely, it's the most important thing."

Jennifer, 43 who is dating back-up dancer Casper Smart, 25 - also revealed that praise from her kids means more to her than from anyone else in the world.

She explained: "You know, my daughter gets very excited [when I perform] and then my son says nothing. But then, like, we'll be in the car randomly, and yesterday he says to me, 'Mommy, you're a great singer.' And I was like, 'Thank you, baby.' No fanfare with it... just matter-of-factly, 'I think you're good.' And of course, that made my day."
