LATEST: The mystery behind the eye patch sported by Britney Spears' former husband KEVIN FEDERLINE has been solved - he has a nasty case of 'pink eye'. The rapper/dancer, who has been handed physical custody of the couple's two young sons, wore the unusual accessory during a court hearing in Los Angeles on Wednesday (03Oct07). But a pal reveals Federline is suffering from the highly contagious ailment, also known as conjunctivitis. A source tells Usmagazine.com, "(Kevin) had strep throat (sore throat) all last week and then got pink eye. It's crazy. He's not doing too well physically but he's trying to get better as he has to leave next week to tape (U.S. TV show) One Tree Hill again."
