'Game of Thrones' star Sophie Turner engaged to Joe Jonas

— -- Joe Jonas apparently proposed to British actress Sophie Turner, and she "said yes."

The couple announced their engagement Sunday in a tender Instagram post showing what appears to be a woman's hand, sporting an engagement ring, over a man's.

Turner, the 21-year-old actress who plays Sansa Stark on the hit show "Game of Thrones," captioned the photo, "I said yes."

The 28-year-old Jonas posted the same photograph and wrote on his Instagram, "She said yes."

Jonas's brother, Nick, chimed in with congratulations over Twitter: "Ahh! Congratulations to my brother... and sister in law to be on your engagement. I love you both so much."
