British actress Lena Headey has given birth to her second child, a daughter.

The New York Post said she was not able to attend the Game of Thrones panel at Comic-Con in San Diego this week because she was having her baby.

"Just fallen in unconditional heartbreaking divine love for the second time," the 41-year-old actress tweeted Friday.

Headey has a 5-year-old son named Wylie with her ex-husband Peter Loughran. She has not publicly revealed the identity of her newborn's father.
