Jennifer Lopez has reportedly made Casper Smart sign a confidentially agreement.
The 43-year-old popstar - who has gotten divorced three times and recently celebrated her one year anniversary with her 25-year-old dancer boyfriend - is said to be taking no chances about their future together and asked him to sign a non-disclosure agreement.
A source told gossip website RadarOnline: "Casper signed a non-disclosure/confidentiality agreement when he began working for Jennifer Lopez, as she requires all of her employees to do.
"Jen has been around long enough to know that anyone she dates could possibly turn on her and choose to go to the press if the relationship sours."
The insider revealed that Casper was only too happy to sign the legal document - which will prevent him for ever discussing their professional and private relationship if they split - much to Jennifer's delight.
The source said: "Casper had absolutely no qualms about signing the agreement, and has told Jen on multiple occasions that even if he didn't work for her, he would have signed the contract. Jen loves him even more for that."
The couple - who are currently in Germany on European leg of the singer's 'Dance Again' tour - began dating just months after Jennifer separated for her third husband of seven years Marc Anthony with whom she shares four-year-old twins Emme and Max.
