Jennifer Lopez: I'm Ready to Spend My Vegas Money ... On a New Crib!

Jennifer Lopez is on the hunt for a new house, and she's clearly ready to open the bank vault.

Our real estate spies tell us, J Lo went house shopping over the weekend in Bev Hills and Bel Air, looking for cribs in the $20 million range.

Check out the estate (above) owned by movie producer Frank Mancuso, Jr., whose dad ran both Paramount and MGM. We're told J Lo breezed through this property -- listed at a cool $22.9 mil -- along with several others, but isn't jumping to make an offer. She's still looking.

The Mancuso property isn't a bad choice -- it's a 14,000 square foot home on 3.5 acres in Bev Hills, behind gates with neighbors including Channing Tatum, Demi Moore and Harry Styles.
