"That's a wrap on Faith for Spring Breakers!!!! Whew craziest experience but amazing. Can't wait to see it..." she tweeted on Friday, posting a photo of the film's clapper board.
The 19-year-old, who was named Favorite TV Actress and Favorite Female Singer at the Kids' Choice Awards on Saturday night, celebrated her wins and the film's wrap with a new hairdo.
On Sunday, Selena said goodbye to the wavy style she'd been sporting and showed off her new hair extensions by celebrity hairstylists and Nine Zero One Salon owners, Nikki Lee and Riawna Capri. "Spring breakers is done now hairs done for the next movie! :)" she tweeted.
According to IMDB, Selena's new hair is for her role in "Aftershock," in which she'll play one of six friends who struggle to survive after an earthquake hits Chile.
