J. Lo's got a swanky new bachelorette pad!

In late August, Jennifer Lopez, 42, purchased an $18 million mansion in the Water Mill area of The Hamptons, New York. The 14,000-square foot home features seven bedrooms and nine and half baths.

Built in 2010 by architect Richard Perrillo of East End Builders, the shingle-style home sits on two acres of land and is surrounded by water.

Other amenities include heated marble floors in the master bath, several walk-in closets, a formal dining room, a library with white oak paneling, seven fireplaces, a media room, dockage on Mecox Bay and a pool.

The property also boasts a first floor guest suite with garden views, an elevator and an attached three-car garage.

The American Idol judge -- currently shooting the movie Parker in Palm Beach, Florida -- won't be settling into her new digs with three-year-old twins Max and Emme just yet.

"She is moving in in a few months," a source tells Us Weekly.

Though she's new to the neighborhood, Lopez has been visiting The Hamptons for years. Less than a month after announcing her split with hubby Marc Anthony, 41, in July, the "On the Floor" singer reunited with her ex at Sagg Main Beach in Southampton, New York.
