As Us Weekly previously reported, the couple, who began dating at the end of a year ago, revealed their engagement on Instagram on Sunday, October 15, sharing the same photo of Turner's hand, with her new bling, on top of the DNCE singer's. "I said yes", Sophie wrote in her caption, which flaunted her $25,000 diamond ring, with Joe posting a similar post shortly thereafter: "She said yes".

"I said yes", Turner, 21, captioned the photo. Everyone loves them together.

(Maisie Williams, her on-screen sister, is her best friend-they embrace the portmanteau Mophie and share a tattoo commemorating the date they were cast.) "It's like the carpet is being taken away underneath you", Turner says.

Jonas, 28, and Turner, 21, began dating past year and have since traveled to London together to meet her parents and spent Thanksgiving with the Jonas clan at the California skiing destination Mammoth Mountain. "He is really so in love with Sophie and she's so in love with him".

It comes after it was revealed that Joe's friends and family are "thrilled" he's engaged to Sophie.

For the first six seasons of GOT, her character was the biblical Job of Westeros, enduring horror after horror, including a very controversial brutal sexual assault in season five. She's young but is beyond her years and is insane, crazy mature. I'm happier than I've been in a very long time.

"They are madly in love". And people I've met recently in my life have drawn me out of that. I very much isolated myself for a while and forgot what was fun.
