The Game of Thrones star, who plays scheming Cersei Lannister in the hit TV show, is currently expecting her second child and she has written an article for Plan International USA, a charity which works to help children around the world and promote equal rights for girls.

In the article, Headey predicts a bright future for her little girl in a world where women are treated the same as men.

Headey writes, "I am having a baby girl in six weeks. You have all been so lovely in your messages to me, and I thank you for that. My daughter will have freedom of choice. She will be free to dance, to sing, to be educated in the fields that spark her passion, to marry if she wants, to marry WHO she wants, to remain single, or to fall in love with another woman. She'll be able to wear what she wants, put on lipstick, and read books that spark debate and expand her mind. She will be loved, protected, respected, and celebrated.

"All these things that should be, and will be, basic human rights, are a promise to my daughter. My humble request is that you give what you can and maybe - just maybe - we can bring about the change we all wish to see."

Headey is also mother to a four-year-old son named Wylie from her marriage to ex-husband Peter Loughran.
