The 34-year-old actress, now, a known face internationally, met the "U Remind Me" hitmaker for an upcoming event Global Citizen Festival, which the duo is hosting.
Priyanka took to Twitter to share a photo of herself posing with Usher, 37.
"So fun "ushering" in the day with you! Lol! Super proud to be hosting #GlobalCitizen with @Usher and so many others!" the "Quantico" star captioned the picture.
The pair will be seen on American talk show, "Today", where they will talk about the festival.
