New Delhi, Nov 3 : Welsh actress Catherine Zeta-Jones has revealed that if she does not have any food, she gets very “upset”.

Zeta-Jones, 39, who is married to actor Michael Douglas and has two children with him, admits that she gets angry if she misses her mealtime, the China Daily reported.

“I’m pretty easy-going, which comes from all those years of doing theatre. I''m not a grandiose movie star at all, but I do like to know when lunch is going to be,” she said.

“It’s really important because I get the shakes when my blood-sugar levels start to drop. If I don''t get food when I should, I get upset,” she stated.

But her anger is not limited only to food, as The Mask of Zorro star also revealed that her children — 8-year-old Dylan and 5-year-old Carys — know never to cross her because she can be strict.

“I’ve realised that you can actually say what you need to say and people can tell a lot from my tone of voice. My kids know when I raise my finger or do ‘the eyes’ that I mean business. I don''t put up with much. I''m kind to everybody. But if you cross me, you know,” she added. (ANI)
