“First I’m blessed with an incredible future brother-in-law, and now such [a] beautiful, inside and out, future sister-in-law,” Turner, 22, wrote on Instagram Saturday. “I’m so excited to welcome you into the family @priyankachopra . I love you both @nickjonas.”
Her loving message came with a picture of the future Mr. and Mrs. Nick Jonas, which showed the pair embracing as she placed her hand (and massive engagement ring) on his chest.

“Future Mrs. Jonas. My heart. My love,” he wrote in the caption, while the actress swooned. “Taken.. With all my heart and soul.”
Their post comes three weeks after PEOPLE broke the news that Nick had proposed after shutting down Tiffany and Co.’s London store to buy her stunning engagement ring. According to a source, Nick popped the question in July while celebrating the Quantico actress’ 36th birthday in London.
“They are so happy,” the insider said of the future spouses, who began dating in May.
“His friends and family have never seen him like this, and they’re all really excited for him. He’s definitely very serious about her,” a separate source added.
Turner wasn’t the only one celebrating Nick’s big news on Saturday. Joe, 29, also had nice things to say, writing on Twitter, “I couldn’t be happier for my brother. Welcome to the family @priyankachopra We love you ]]>🤗🙏🏼🎉
