Carla Jeffery, an actress recognized for her role as cheerleader Bree in the Disney Channel movie franchise "Zombies," has died. She was 33.

Her twin brother, Carlon Jeffery, also an actor, shared a statement mourning his sister, which he reposted on social media. He included a clip of Jeffery on a beach and a screenshot of a text message from him to her. "I just want you to know how proud I am of you. Your resilience, your grace, your infectious smile that lights up a room," the text read. "You are truly a light that shines bright. Don't let anyone dim that light, even yourself."

Co-stars paid tribute to Jeffery, with Chandler Kinney, who played Willa in "Zombies," writing that the actress's death "doesn't feel real." Kinney described Jeffery as "the sweetest, most sparkly gal" who "made every day better and brighter with your infectious positivity."

Kinney added, "I think part of why you brought such effervescence to Bree (aside from your immense talent) is because that's really who you were in your heart; a bubbly, vivacious heart-of-gold cheerleader who loved nothing more than to uplift those around her." Milo Manheim, who played Zed, shared photos with Jeffery, captioning them, "Love you Carlaboo, the sweetest, kindest, most loving person."
