The actress became engaged to Williams in June (10), shortly before they flew out to Iraq for a morale-boosting visit to U.S. troops serving in the Middle East.
The couple has since been busy promoting new movie The Dry Land, which was written and directed by Williams and stars Ferrera.
But their hectic work schedule means the stars’ nuptials have taken a backseat to their new release.
Ferrera tells People.com, “If there is a scale between 0 and 10, I’m at like negative 10. I haven’t gone there and (am) not thinking about it (wedding planning). We got engaged and then left for Iraq the next day.
“We both talk about it (the wedding). It’s so crazy because right now the only thing I’m sure of is that there will be a cake and music!”
