English actress Sophie Turner and beau Joe Jonas put a ring on it!

JUST WEEKS AFTER GAME OF THRONES couple Kit Harington and Rose Leslie announced their “forthcoming marriage,” their co-star Sophie Turner and her boyfriend, Joe Jonas, shared their engagement news via co-ordinated Instagram posts. Turner, 21, captioned a photo of her hand—featuring sparkler—resting on the singer’s hand with “I said yes.” Jonas, 28, posted the same photo, with the message “She said yes.” Among the first to respond were Jonas’s brothers, Kevin and Nick—who shared the photo on Twitter with “Congratulations to my brother … and sisterin-law-to-be on your engagement. I love you both so much.” Adds a source: “Everybody’s very, very happy for them and their family and friends are all thrilled.” ■

“He was such a dater before her but their relationship was much different from the start,” a source tells WHO of the couple (on April 29). “She was just the one for him.”

The couple coordinated their news, posting this photo at the same time on Instragram on Oct. 15.
