Lena Headey's ex-husband is reportedly demanding she pay his legal fees after claiming she earns $1 million per episode for her role on 'Game of Thrones'.

The 43-year-old actress divorced from Peter Loughran in 2013 after six years of marriage, and are now locked in a heated custody battle over their six-year-old son Wylie. Peter is now reportedly filing new court documents asking that the star cough up the $40,000 to pay for his legal fees.

TMZ is reporting that the documents claim Lena makes $1 million per episode on the HBO fantasy drama - in which she plays Cersei Lannister - and can therefore afford to part ways with the money Peter needs.

Loughran believes it's "only fair, since he's jobless", whilst Lena reaps the rewards of starring in a hit television show.

Claims of Lena's large income comes after it was previously reported that the main cast of the show - including Lena as well as Peter Dinklage (Tyrion Lannister), Kit Harrington (Jon Snow), Emilia Clarke (Daenerys Targaryen), and Nikolaj Coster-Waldau (Jaime Lannister) - were heading into Season 7 on a pay cheque of around $500,000 per episode.

Last month, things took another bitter turn in the custody battle after Lena was forced to bring a signed letter from 'Game of Thrones' executive producer Bernadette Caulfield to a judge after Peter questioned their current custody order.

At present, Lena is only allowed to take her son to the UK whilst she is filming, and Peter claimed shooting should have finished by now, before Lena produced the letter confirming she was needed until at least January 31 2017.

TMZ also reports that the judge for the case has yet to rule on Peter's request for his legal fees to be paid by Lena.
