Photographers told Us Weekly that Duff and Comrie were strolling through Beverly Hills over the weekend when they spotted the 22 Jump Street actor leaving a restaurant.
According to the publication, the Canadian hockey player noticed Hill and tried to get his attention by calling his name. However, the Oscar-nominated actor failed to look back.
Duff and Comrie, who separated in January but remain friends, weren't fazed by the incident and reportedly continued on with their day after the fact. The 26-year-old actress was later seen at Beverly Hills Nail Design and grabbing a green juice.
