Jennifer Lopez has been soaking up the sun in Miami this week, and showing off her smokin' hot bikini body while she's at it. The singer was spotted at the pool with her kids and beau Casper Smart today, and she wore a stunning black bikini for the occasion. Hot!

Lopez, who turned 43 this summer, held daughter Emme's hand as they entered the pool and splashed around with son Max, too. The star's twins will turn five soon and they're definitely growing up and getting big!

Lopez has been performing and relaxing in Miami for the last few days. She got some quiet time at the pool with Smart Saturday afternoon, but the star has mostly been spending time with her kids, it seems. Friday the happy family splashed around in the pool again and Emme had a blast getting thrown around by 25-year-old Smart. He put his big muscles to good use, that's for sure!
