The 32-year-old former Miss World took to Instagram to reveal the cast of the upcoming ABC show, which also features Tate Ellington, Graham Rogers, Johanna Braddy and Yasmine Al Massri.
"Cast list... #Quantico #PrepDay #Pilot," Priyanka wrote alongside a horizontal collage of photographs of the actors in the show.
It has been reported that McLaughlin, also 32, will play Priyanka's love interest on the series. The actor has previously starred on the J J Abrams and Alfonso Cuaron's NBC drama 'Believe'.
Josh Safran of 'Gossip Girl' fame will pen the script and executive produce the ABC Studios and Mark Gordon Company drama alongside Mark Gordon and Nick Pepper.
Marc Munden will direct the pilot.
The drama centres on a group of young FBI recruits, who battle their way through training at the Quantico base in Virginia.
Priyanka will play Alex Weaver, a brilliant but haunted FBI trainee whose past boils to the surface soon after her arrival at Quantico.
