Nick Jonas and Priyanka Chopra made their engagement official on Saturday with a roka ceremony, and the celebrity couple couldn't look more in love.

Taking to his Instagram Stories following the weekend celebrations in India, Jonas shared a video of Chopra dancing with girls at an orphanage in Mumbai.

The 'Jealous' hitmaker captioned the sweet moment, "St. Catherine's Orphanage today. My heart is full."

While Chopra entertained with her Bollywood moves, Jonas opted to give the young girls a private concert as the soon-to-be Mrs Jonas smiled broadly and clapped along with the crowd.
