"Wow. First I’m blessed with an incredible future brother-in-law, and now such a beautiful, inside and out, future sister-in-law," Turner captioned the snapshot showing the Quantico actress and the "Chains" singer gazing into each other's eyes while her stunning new diamond ring sparkled on her hand.
"I’m so excited to welcome you into the family @priyankachopra," she added. "I love you both @nickjonas."
The huge celebration, which is known as a Roka ceremony in India, included members from both stars' families, and was covered extensively by Indian Express, who ran numerous snapshots from the grand occasion.
