As the Water for Elephants star, 35, left church on Mother's Day with her husband Jim Toth and children Ava and Deacon, she sported a soft cast on her left foot.
"She twisted her ankle and is in a walking cast temporarily. Nothing serious," Witherspoon’s rep tells PEOPLE.
Witherspoon was married in March at her Ojai, Calif., home.
