Cersei Lannister is pregnant... in real life.

41-year-old actor Lena Headey, who plays the ambitious and ruthless Queen Regent in Game of Thrones, has confirmed she is expecting a baby this summer.

Lena is already the mother to four-year-old son Wylie (whose father is Lena's ex-husband, musician Peter Loughran).

Lena has not revealed who the father of her second child is.
