'Game of Thrones' star Aidan Gillen snaps at talkshow host after she calls his girlfriend his 'fiancée'

Westeros has always been full of formidable characters, but none have rivaled the notorious Petyr Baelish - better known as Littlefinger - in the manipulative department.

He went from the number one pimp in the King's Landing brothels to Sansa's political advisor after Jon left Winterfell in her charge. And many fans breathed a collective sigh of relief when he finally met his end in season seven before he caused the Starks even more heartache.

Played by Irish actor Aidan Gillen, the 50-year-old recently appeared on British talk show Lorraine to discuss his next big role less than a month before the final season of Game of Thrones airs.

However, when the Scottish talk show host accidentally referred to his girlfriend as his fiancée, he was less than impressed.

To see Gillen's incredibly awkward response to the slipup, check out the video below: 

In the clip above, Lorraine asks Gillen, "So you're taking on a new role, you're singing with your fiancée?"

To which he responds, "She's not my fiancée, she's my partner… I'm not looking at a career in music."

Clearly embarrassed by her mistake, the 50-year-old apologizes and the actor says it's "all good". She then turns to the camera and says, '"So sorry Aidan, keep me in the loop next time!"

Needless to say, viewers of the show had a lot to say about the awkward exchange on social media:

Gillen had appeared on Lorraine to promote his new Syfy drama Project Blue Book - a TV series centered on the UFO phenomenon which appeared in the US in the 1950s.

Its release date in the UK has yet to be confirmed, but it appeared on the History channel in January and has been renewed for a second season.

"Well I'm open-minded," the actor said when asked about his opinion of extraterrestrial life. "I'd be very surprised if we were alone in the universe."
