Jennifer Lopez is having SERIOUS stalker problems. 49-year old John Dubis of Rhode Island already had a restraining order filed against him by J.Lo but totally disregarded that when he broke into her home and decided to stay for a while! The scary part is J.Lo was totally unaware that this man was staying in her pool house until workers noticed a strange man on the property and called police. Dubis was charged with second-degree burglary, first-degree criminal contempt, fourth-degree stalking and possession of burglar tools.
