Britney Spears' ex Kevin Federline was forced to cancel a family yachting trip last month (Oct07) after his sons contracted the eye infection that has plagued their parents. Sean Preston, two, and Jayden James, one, were enjoying a presailing barbecue when Federline noticed them robbing their eyes. He immediately realised both boys had pinkeye because he was the first member of the family to suffer the infection. Spears also spent a week hiding her infection behind dark glasses. A source tells America's Life + Style magazine, "Kevin had originally booked a yacht ride for everyone, but they had to cancel it because of the pinkeye. "Everyone thinks it (infection) came from Britney's dog. The dog had it first, and then everyone else seemed to get it - including Britney."
