My Sister the Vampire: Re-Vamped! s a 2017 film. This film stars Kira Kosarian and Amber Montana.


The secret is out! Cheerleader Olivia and Vampire Ivy are twins! Now that Ivy and Olivia have told their friends that they're twins, they have to come clean to their adoptive parents. But Ivy's dad doesn't even want to meet Olivia!
