Real LI

Call it the Brookville
baby boom -- not just of twins Jennifer Lopez is supposedly expecting but the boom of hammers and nails at her and Marc Anthony's North Shore estate. A tipster tells Real LI that the couple has been pouring millions of dollars into renovating their property -- which Anthony bought in 2000 for $3.7 million -- from the grand gate and brick wall at the entrance to improvements on the pool, cabana and driveway. And under his real name Marco Muniz, Anthony recently sought permission "to install an automatic sprinkler installation throughout a three-story building" at the estate. Could all this have to do with the reported pregnancy? Maybe, but last year Vogue Living reported that even after extensive renovations were done to the house featured in that magazine's shoot, Lopez thinks the home is "a work in progress. I think any home is."
