Spoiler Alert! "I Know What You Did Last Summer" surprise cameos revealed!

SPOILER ALERT! Proceed with caution if you’re waiting to watch the new slasher sequel.

“I Know What You Did Last Summer” returns with a sequel that delivers on the gore and familiar faces from the original murder mystery. Not only do Jennifer Love Hewitt and Freddie Prinze Jr reprise their roles, but Sarah Michelle Gellar and Brandy make surprise cameos in the new film.

During their press run, Madelyn Cline (Danica) tells our reporter, Courtney Tezeno, how she found out she would be sharing a scene with Gellar, who played the iconic role of Helen Shivers.

Plus, we quizzed the cast on which Brandy Norwood song best describes how their character dies or encounters the fisherman killer. Brandy appeared in the 1998 film as Hewitt's bestie in “I Still Know What You Did Last Summer,” and has a surprising appearance in the new horror flick.

Watch the clip to hear which songs they chose!

Chase Sui Wonders (Ava), Tyriq Withers (Teddy), Jonah Hauer-King (Milo), and Sarah Pidgeon (Stevie) star in the latest slasher thriller in theaters July 18.
