Game of Thrones star Lena Headey has given birth to her second child.

The British actress took to Twitter on Friday to share the news with fans in a brief message. She simply writes: "Hello peeps . All good. Just fallen in unconditional heartbreaking divine love for the second time."

Headey announced her pregnancy in February (15) and recently revealed she was having a girl, but she has yet to identify the baby's father.

The 41-year-old is also a mum to son Wylie, five, with her ex-husband Peter Loughran.
