Joe Jonas deals with Sophie Turner's 'Game of Thrones' ex at premiere

A love triangle is nothing new, but when it's a "Game of Thrones" love triangle, well, then you have something special on your hands.

All jokes aside, Joe Jonas posted the cutest picture on Instagram of his fiancée Sophie Turner and her on-screen ex Jack Gleeson, who played the despised King Joffrey.

You know, the one who tortured Sansa Stark on the show to no end?

Well, in real life, Gleeson, who stepped away from acting after being killed off the show, seems to be a swell guy.

Jonas joked about the reunion, writing, "WTF I thought this dude was dead... #KingJoffrey."

In the pic, Turner is draped around Gleeson, both smiling, ignoring her future husband. It's all in good fun.

Wednesday night, the premiere for the eighth and final season of HBO's "Game of Thrones" took place at New York City's Rockefeller Center and everyone got emotional.

Before arriving to the big night, Jonas posted another grab from the night, this time no jokes, just all support.

"Congratulations babe!" he wrote next a video of her arriving at the big red carpet.

Now, fans will wait just over a week for the show to return April 14 and see who takes the throne. One thing is for sure: it won't be Jonas or Joffrey...

Though Westeros could use a little Jonas Brothers.
