Games of Thrones star Sophie Turner and grace park sex videomusician Joe Jonas are officially engaged.

"I said yes," the 21-year-old actor posted on Instagram on Sunday, along with an image of the two holding hands with a GIANT rock on her finger. (It's unclear if Jonas' hand was being held down by the weight of the stone or with love.)

The DNCE singer posted the same photo to his Instagram with the witty caption: "She said yes."

It's unclear exactly when the two started dating, however fans started speculating about a relationship when the couple were spotted at a Kings of Leon concert in the Netherlands in November, according to People.
