The twosome joined the rest of their cast mates inside for the world premiere of the flick, before heading over to Hollywood High for a very Prom-esque after-party. Raini‘s brother, Rico, is also pictured below.
Kylie plays Jordan, Tyler Barso’s girlfriend and one half of the most popular couple at Brookside High.
Raini, 17, plays Tess, a freshmen looking to help her step-brother get a date for the big dance.
Prom opens everywhere on April 29th.
