In some photographs surfaced online, the duo can be seen walking hand-in-hand during their low-key outing.
While Priyanka opted for a black-and-white checkered dress for the outing, Nick, on the other hand, looked pretty relaxed as he walked next to Priyanka donning a white shirt and khakhee pants.
Priyanka and Nick, who have been romantically linked to each other ever since 2017 MET Gala, where they walked the red carpet together in Ralph Lauren designs, landed in India on Thursday night.
Earlier this month, Priyanka was spotted at Nick's cousin Rachel Tamburelli's wedding in New Jersey.
The duo spent time with Nick's family at a brunch.
Priyanka and Nick are yet to confirm their relationship.
