Rihanna, who is a fan of the A&E drama, sent a special video message from her bedroom revealing her exciting new acting gig.
"Hello Comic-Con! It's bad girl Rih Rih and let me tell you what the bad b*tch is about to do. I'm about to check into the Bates Motel very soon," she said. "Guess what else? Guess who's playing Marion?"
"We wanted to thrust the iconic role into a contemporary spotlight and redefine it in a meaningful and exciting new way. We also heard Rihanna was a fan of the show, and we were huge fans of hers, so it was the perfect collision of creativity and fate," said executive producers Carlton Cuse and Kerry Ehrin in a statement.
Rihanna also stars in the upcoming sci-fi movie Valerian and the City of a Thousand Planets, which hits theaters July 21, 2017.
Vera Farmiga, whose character Norma was killed in the final episodes of season four, will also return in the fifth and final season and serve as executive producer.
Bates Motel begins filming this fall and will return in 2017 on A&E.
