Wylie Elliot Loughran is Lena Headey’s son with her former spouse Peter Loughran. His parents protect his privacy and prefer not to share much information about him.
Following their breakup, Lena and Peter made a joint-custody arrangement and the latter allowed his ex-wife to take Wylie with her when she was shooting Game of Thrones around the world though he accompanied them and demanded that Headey paid for him.
By the way, when Lena was filming the first season of the legendary show, she was pregnant with Wylie. The production team did its best to hide the growing baby bump by keeping the camera frame above her waist and making her character’s costumes with large billowing sleeves that could hide her pregnancy.
A curious fact: Lena suffered from postnatal depression soon after Wylie drew his first breath.
