"Game of Thrones" actress Natalie Dormer stopped by "Jimmy Kimmel Live!" Tuesday night, where she confirmed that season 6 of the beloved HBO series had finished filming. While the actress was at the late night talk show to discuss her new film "The Forrest," the conversation naturally went to the series and the actress might have revealed a spoiler about the super secretive new season.

"Game of Thrones" films the show at different destinations around the world, but Dormer usually shoots the scenes for her character Margaery Tyrell in Belfast, Northern Ireland. The last time Dormer's character was seen in Season 5, she was sitting in a jail cell, but the actress confessed that she "was in Spain a lot this year" for season 6.

"Is that a bit of a spoiler?" Kimmel asked the actress.

"There are dungeons in Spain," Dormer laughed to Kimmel as she brushed off the host's comment.

"But why would you need to go to Spain for a Dungeon?" Kimmel replied.

Dormer also revealed that she was a huge fan of the series before she joined in season 2 and that she tried to avoid spoilers of the show just like everyone else.

"I watched season 1 like a fan, like you. So when I joined them in the second season, I wanted to go back to feeling like a fan, so I stopped reading other people's storylines," Dormer said. "I only read the scripts that are relevant to Margaery and Highgarden and King's Landing. So when the show airs, I'm sitting on the couch watching it like you."

Dormer did admit that her plan had a couple of flaws to it.

"I'll be sitting in the hair and makeup trailer, and someone will show up and I'll be like, 'What are you doing here?'" Dormer said. "Oh my god, you're back? I gotta leave.'"
