“Game of Thrones” star Lena Headey just welcomed a little princess into her life. The actress, who plays Queen Mother Cersei Lannister on the hit HBO series, gave birth to her second child, a baby girl.

Headey, 41, took to Twitter to share the news with her fans in a heartwarming tweet:

The star announced in February that she was pregnant, and in late May she confirmed that she was expecting a daughter. She revealed the news in a blog post titled “My Daughter” on the Plan International USA site.

“I’m having a baby girl in six weeks,” she wrote. “You have all been so lovely in your messages to me, and I thank you for that.”

Lena Headey has been very vocal about her desire to expand her family. She’s already a mom to 4-year-old son Wylie, whom she shares with her ex-husband, musician Peter Loughran. In 2014 she told the Telegraph that she loves “being a mum” and that her “dream is to have more kids.”
