Jennifer Lopez kicked off her Labor Day weekend with a sexy black two-piece, complete with a stylish shoulder strap.

The 42-year-old singer, who is in Miami for her final stateside shows with tour mate Enrique Iglesias, snuck in some precious R&R on Saturday at a South Beach hotel.

But Lopez wasn’t alone at the pool. Who else joined the “On The Floor” singer for some quality pool time?

Two days after rocking her yellow bikini at the pool, Lopez was once again joined by her adorable 4-year-old twins Max and Emme, Lopez’s 25-year-old boyfriend, Casper Smart, also took a much-needed dip in the water.

On Friday, Lopez sent out a special Labor Day tweet to more than 10 million followers.

“Happy Labor Day weekend to all my LOVE!RS!” she wrote.
