The star of That '70s Show, 36, popped the question last week to actress Ashley Hinshaw, and she said yes, a source confirms to PEOPLE.
Hinshaw, 26, has had roles on True Blood and Agent Carter, and recently joined the cast of HBO's True Detective for its second season.
Meanwhile, Grace has been shooting the indie musical comedy One Shot with Taye Diggs, Anne Heche and Rob Riggle.
Grace and Hinshaw stepped out together on Saturday at the Art of Elysium's Heaven Gala in Santa Monica, California.
A representative for Grace could not be reached for comment.
