Veteran Tv producer and film distributor Sandy Frank is suing his former fiancee for the return of the $300,000 (£187,000) engagement ring he gave her.
The Lassie producer has filed papers at Manhattan Supreme Court in New York City claiming the ring he gave to Patricia Berg was not returned following the couple's split in June, 2009.
In the lawsuit, Frank orders Berg to hand back the piece.
His lawyer, Suzanne Bracker, insists the engagement was "very short-term", adding, "He was extremely generous to her.
"He was a gentleman and she should behave as a lady. A lady does not keep what does not belong to her."
Frank subsequently wed another woman in 2010, but they later divorced.
There are currently five separate teams working on 'Game of Thrones' projects at HBO.
She's a big fan of the band and this week she got to perform with them.
