Lena Headey is pregnant with her second child.

The 'Game of Thrones' star - who has four-year-old son Wylie with ex-husband Peter Loughran - has confirmed she is expecting another baby in the summer and called for the paparazzi to give her some privacy throughout her pregnancy.

The 41-year-old star - who plays Cersei Lannister in the HBO drama series - said in a statement to PEOPLE: ''I'm happy to confirm that I'm having my second child this summer.

''I only hope that this announcement can help me to regain some of the privacy I have recently lost to prying photographers and ask that they please respect my privacy and let me enjoy this time.''

Lena - who will reprise her role as Cersei in the fifth 'Game of Thrones' season in April - rarely speaks about her personal life and divorced Peter in 2013 after six-and-a-half years of marriage.

The star previously dated fellow actor Jason Flemyng for nine years after meeting him on the set of 1994 movie 'The Jungle Book' - in which she portrayed Kitty Brydon and he played Lt. John Wilkins - and got a tattoo of his name in Thai during their relationship.

What's more, Lena was also once engaged to 'The Departed' star Johnny Cicco.
