New Delhi, Apr 10 : Halle Berry doesn't believe celebrities who claim that they stay slim without exercising.

The 42-year-old actress - who has a one-year-old daughter, Nahla, with her partner Gabriel Aubrey - says she works really hard to keep extra pounds at bay, reports The China Daily.

She said: "God bless them if they''re telling the truth. It''s questionable if they are. I always had to diet. I''m diabetic, so it''s a lifestyle for me anyway just to stay healthy and not end up in the hospital."

Halle had to change her diet and exercise regime after giving birth to ensure she didn''t pile on the pounds.

She revealed to Harper''s Bazaar magazine: "Having a baby takes so much from you. It''s the most glorious thing you''ll ever do, but the aftermath is not so glorious! So now I''m having to exercise, eat a little bit differently, take a lot more vitamins.

"I used to work a lot because I had nothing better to do. What I''ve learned, especially by having a baby, is that you can''t bring that stuff home anymore." (ANI)
