A preview of the new CW show ‘Hellcats’, starring Ashley Tisdale and Aly Michalka of 78violet, has been posted online. The series will be airing Wednesdays this Fall. “‘Hellcats’ is the world of competitive cheerleading, and I play Savannah Monroe,” Tisdale told MTV News. “She’s the captain of the cheerleaders and Marti, played by Aly Michalka, has lost her scholarship. So she has to join cheerleaders. And it’s a lot of fun. It’s a drama, but it still has the fun energy. It’s very fierce.” Watch the preview via YouTube below.
