The 1997 Hollywood blockbuster had a scene featuring Rose DeWitt Bukater (Kate Winslet) and Jack Dawson (Leonardo DiCaprio) spreading their arms wide open at Titanic ship's edge.
While Priyanka got her pose right, actor-filmmaker Farhan Akhtar played a photo bomber.
"My titanic moment... I'm flying Jack... Where is jack? Photo bomber @FarOutAkhtar @RanveerOfficial busy #DDDTitleTrack," Priyanka captioned a photograph that she tweeted.
The movie also features Anil Kapoor and Ranveer Singh.
