The Queen no longer has a king.
Headey, who plays Queen Cersei Lannister on the HBO fantasy series, cited "irreconcilable differences" in her split from musician Peter Loughran, according to court documents filed in Los Angeles obtained by the magazine.
According to documents, the couple has been separated since 2011. Headey, 38, and Loughran married in May 2007 and welcomed their son, Wylie, in March 2010. Headey is seeking joint legal and physical custody of Wylie.
