The two were pictured sharing a laugh, outside the Microsoft Theater. While Priyanka was seen wearing an off shoulder white top and blue denims, Tom sported a black t-shirt and jeans.
The confirmation of sorts comes from another photo that Priyanka shared of herself on stage with her presenting partner.
The blurry picture shows her 'partner' wearing all-black ensemble, seeming confirming that it's the "Thor" star.
"Rehersals #Emmyswithpc keep guessing... Btw the blur is the point!" the 33-year-old "Quantico" actress captioned the photo, hinting that the blur was intentional.
Emmy Awards, which honour the best on television, are set to go live tomorrow morning. Tom, 35, is nominated for the outstanding lead actor in a limited series or movie for his work in "The Night Manager"
