Berry, who confirmed her pregnancy in April, said that Mother’s Day is a fun holiday for her because she doesn’t have to do the party planning.

“My family gets together and they get to plan the day for me, and I love that,” she told reporters on Saturday while hosting the 20th Annual EIF Revlon Run/Walk for Women.

“I’m the planner and I’m the one that organizes, and on Mother’s Day I get to just be taken care of.”
