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.
