A-lister Jennifer Lopez is one hot mama who looks like she hasn't aged a day in her life! The mom of 10-year-old twins Max and Emme will turn 49 years old this summer and, now that she's inching closer to 50, can't help but think about the realities of aging. "Listen, at some point, I'm going to age," she recently joked to Emmy Magazine. "They'll say, she looks old! But, right now, I'm holding it together."

Funnily enough, the Shades of Blue actress said her boyfriend, Alex Rodriguez, has agreed that she doesn't seem to be aging. "The other day, Alex was across the lawn, and I brought him something, and then I ran away. And he said, 'You run like you're 25 years old,'" Jennifer recalled. "I haven't stopped that pace, so I'm still at that pace, I guess. When things start aching more, it'll be different."

As a worldwide entertainer who's constantly performing onstage, it might be awhile before Jennifer feels those aches. "I'm good at the showgirl stuff. I’m good at being onstage, doing a photo shoot, the stuff I need to be good at for my job. And I enjoy it," the former American Idol judge said. And with new music, a Las Vegas residency, and shows on NBC, Jennifer has no plans to slow down.

"I know how to work it and make it work. But I don’t need to be the center of attention. I'd rather not talk to people at a party. I’m not that person," the singer shared. "I just take it day by day, because it's so much stuff, and I try not to worry about too much."

"When I leave here. I'll go home, have a nice dinner, then I'll go to my bedroom, have a nice bath. I'll have a chocolate cookie with milk, I’ll watch TV. And then I'm like, okay, tomorrow is full out," she added. And Jennifer knows not to take anything for granted, especialy when it comes to her kids.

Jen's fellow World of Dance judge Derek Hough has said, "if her kids are calling or FaceTiming, no matter what is going on, Jennifer picks it up. She can be in the middle of a comment [on the show], and she'll go, 'Oh, my kids are calling me.' Her priority is her family — it’s been a lovely thing to see."
