The happy couple began celebrating with a series of parties and ceremonies, including a night out on the town with fellow engaged couple Joe Jonas and Sophie Turner.

From there, they participated in the puja, a Hindu pre-marriage ritual at Priyanka‘s mother’s home. They will formally wed in a Hindu ceremony over the weekend, followed by a Christian ceremony.

FYI: Priyanka and Nick are both wearing Manish Malhotra World designs at the puja ceremony.
