Some "Game of Thrones" fans were saddened to find out that Sophie Turner and Joe Jonas were engaged after just 11 months of dating. Some fans were "stanning" Turner and her BFF Maisie Williams, who often showed each other a lot of sisterly love, especially on red carpet events. The pair met on "Game of Thrones" and since then became very good friends. In Williams' comment on Turner's Instagram post, the actress called Turner "my beautiful girlfriend." But Williams isn't the only one to react to the Turner and Jonas' engagement.

Demi Lovato commented on Joe Jonas' post announcing his engagement to "Game of Thrones" star Sophie Turner. According to PEOPLE, the singer wrote, "HUGE CONGRATS!!!!! Sooooo happy for the both of you!!!!" Lovato and Jonas were a couple back in 2010, and even starred in Disney's 2008 film, "Camp Rock." Despite their breakup, however, the pair remained amicable, as Lovato is also close friends with Jonas' younger brother, Nick.

Fans even speculate that one of the songs in her new record, "Ruin the Friendship," is about Nick Jonas.

No bad blood

There's definitely no bad blood between Joe Jonas and former flame Demi Lovato, who told PEOPLE that she has "respect for everybody who has been able to [build a career after Disney], especially Joe because of how well DNCE is doing.

He deserves it." While the 28-year old Joe Jonas and 21-year old "Game of Thrones" star Sophie Turner haven't disclosed a wedding date just yet, sources close to the couple say that they are in no rush to get married.
