Wilson and her co-stars from "Pitch Perfect" rehearsed a multi-genre opening medley Friday that features Wilson spoofing last year's films and spinning nunchucks.
Brittany Snow, Anna Camp and Skylar Astin, along with a troupe of gymnastic dancers, joined the first-time host at Sony Pictures Studios to run through four songs not featured in the film. MTV insists on keeping the titles a surprise until Sunday's show.
When the group finished rehearsing, Wilson thrust her fist toward the sky and shouted, "'Pitch Perfect' two!"
A sequel to the musical comedy has not been announced.
Wilson will be joined at the MTV Movie Awards by presenters such as Brad Pitt, Melissa McCarthy, Seth Rogen and Kerry Washington and performers including Selena Gomez. Jamie Foxx, Will Ferrell and Emma Watson will receive special awards at the ceremony, which will be broadcast live Sunday on MTV from 9 to 11 p.m.
