The intruder camped out in 
John Dubis, a 49-year-old man from Rhode Island, was eventually found in the pool house — where he had been camping out — by workers on August 8.
Southampton police said Wednesday that the singer had an order of protection against Dubis, but it is unknown why the order was initially obtained.
After being found on the 3-acre estate, Dubis was arraigned on charges of burglary, criminal contempt, stalking and possession of burglar tools.
He's due in court Aug. 28 and is currently being held on $100,000 bail.
Lopez just purchased the Hamptons estate for nearly $10 million in May.
