With her growing baby bump on full display, Halle Berry
stepped out for a midday Mother's Day celebration in Beverly Hills on Sunday.
Wearing flip-flops and a sleek purple halter dress set off by long metallic chain necklaces, Berry, 46, joined daughter Nahla
, 5, and fiancé Olivier Martinez, 47, for a casual lunch date at Riva Bella restaurant.
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."
