Jennifer Lopez is drawing a line in the sand — paying nearly a grand to rent out a public beach in L.A. last weekend … to keep randos away from her family and children.
Sources tell our sources, Jennifer forked over $925 to the city of Long Beach to rent out Marine Beach on Saturday — 3,400 feet of shoreline — just for her, her kids, her BF Casper Smart and other family and friends.
To keep out the riffraff, we”re told lifeguards marked off the water using buoys — and kept the beach gates locked.
We”re told J.Lo and co. brought their own jet skis for awesome fun times — and even hired a wakeboard instructor.
Meanwhile, a bunch of sad locals stayed home and played with dirt.
