The 35-year-old actress and the 30-year-old furniture designer have split after dating for nearly a year and a half, People reports.
Amy and Ben first dated back in January 2016. The two made their first public appearance together at the Golden Globes later that year.
During an interview earlier this month, Amy told Howard Stern that she and Ben were still together and were talking about marriage.
“We are talking about today,” Amy said. “I love the idea of committing to someone and making that choice and I want to have a family but right now, we are not in talks.”
Amy was not joined by Ben at the premiere of her new film Snatched.
