The film, set to be released on Valentine's Day in 2019, is about a young woman who mysteriously finds herself trapped inside a romantic comedy.
Priyanka showed off her dance moves in a beautiful pink dress and heels on the streets of NYC.
Liam enjoyed a sip of coffee during the dance off. He looked smashing in a dark suit with an open collar.
This movie will most likely be hilarious, as it costars Pitch Perfect's Adam Devine, who was seen waving to the crowds during a break in filming.
Speaking of Pitch Perfect... Rebel Wilson is also part of the cast! She was spotted having a blast in a beautiful form-fitting red dress.
