"Anna and I are sad to announce we are legally separating. We tried hard for a long time, and we're really disappointed," Pratt wrote in a statement. "Our son has two parents who love him very much and for his sakewe want to keep this situation as private as possible moving forward. We still have love for each other, will always cherish our time together and continue to have the deepest respect for one another."
The 41-year-old Faris is reportedly dating cinematographer Michael Barrett. She stars on CBS' Mom.
