US actors Chris Pratt and Anna Faris have announced that they are separating after eight years of marriage in joint statements shared on social media. The couple, who met in 2007 while filming the romantic comedy Take Me Home Tonight, said attempts to save their relationship had failed. "We tried hard for a long time, and we're really disappointed," Pratt wrote in a post on Facebook on Sunday. Pratt, 38, and Faris, 40, were married in 2009. They have a son named Jack. "Our son has two parents who love him very much and for his sake we want to keep this situation as private as possible moving forward," the statement said.
