Nick posted a small video clip as his Instagram story.
According to Entertainment Tonight, the couple has jetted off to India and Jonas is to meet Chopra's mother Madhu.
The hit maker and the actress arrived arm in arm for the family occasion.
Just recently, Priyanka had accompanied Nick to his cousin's wedding as his plus-one and while the news itself had sent the fans into a tizzy, later it was revealed that the actress had also bonded with Nick's family.
Priyanka looking loved up is certainly a blessing for her - after her now cancelled show Quantico came under fire for a controversial episode earlier this month.
Following a very, very secret arrival in Mumbai, PeeCee and the youngest Jonas finally gave the paparazzi a glimpse when the two stepped out for dinner last night. "They weren't trying to be private as they were in a pretty public place, but they were talking to people around them, sitting closely and they both just seemed super happy". Also, some reports suggested that she wanted Nick by her side during her new housewarming grand party which will happen soon. "I'm very fond of children and I want to be able to do that".
