"Future Mrs. Jonas. My heart. My love," Jonas captioned a sweet photo of him and Chopra face to face with Chopra's hand on his chest and a large diamond visible on her ring finger.
"The only way to do this... with Family and God. Thank you all for your wishes and blessings," Chopra wrote alongside an Instagram photo collage of her and Jonas praying and celebrating while wearing traditional Indian attire.
"Taken.. With all my heart and soul," she wrote in another post.
