'Game of Thrones' star Lena Headey files for divorce from Peter Loughran

Lena Headey, who plays the chilly queen Cersei Lannister on HBO's "Game of Thrones," has filed for divorce from husband of five years Peter Loughran. The couple has one child together, son Wylie Elliot.

Headey and Loughran, an Irish singer, married in 2007 and she has his last name tattooed on her left wrist (oops!).

"He's not an actor, he's a normal man," said Headey in one interview. "Well, he's not normal; he's Irish, but you know what I mean. We met at a friend's wedding and had a little dance together; it was pretty serious, right from the start."

Headey, who splits her time between Los Angeles and England, cites "irreconcilable differences" in her divorce filing, according to TMZ.
