It's dark days for House Lannister.

On Wednesday, TMZ learned that "Game of Thrones" actress Lena Headey filed to divorce musician Peter Loughran after five years of marriage. The British actress, who plays conniving queen Cersei Lannister on the HBO fantasy hit, cited "irreconcilable differences" as the cause of the split. The couple have one son, two-year-old Wylie Elliot.

Headey, 38, isn't the first HBO star to make headlines for splitting. Here are seven others, including one of Headey's co-stars on "Game of Thrones."
