Jennifer Lopez is in no rush to marry Casper Smart.Although the 43-year-old singer is deeply in love with her 25-year-old backing dancer, she says she is taking their relationship one day at a time. Speaking on 'CBS This Morning' she said: ''[Usually I'm like] Where is it going? Are we getting married? But now I'm like, maybe it's OK to just be in the moment. Maybe it's OK to enjoy this for right now. Who knows where it's going? There's love here. Relax.'' Jennifer started dating Casper after her split from third husband Marc Anthony and the 'Parker' actress admitted it has been difficult explaining the marriage breakdown to their four-year-old twins Max and Emme. She said: ''It wasn't until recently they started going, 'Where's Daddy?' And I'm like, 'I'm going to explain it to you when you're bigger because you're not going to understand it right now.' And they'll take that. And I said, 'But here's what I do know. Mommy and Max and Emme are always going to be there. Mommy's always going to be there. Mommy's not going anywhere.' And that comforts them a little.''
