Adam Savage, 52, is facing some serious sexual abuse allegations from his own sister, Miranda Pacchiana, 51, but he has denied them all. Miranda filed a lawsuit against the former MythBusters co-host on June 30 and is alleging he sexually abused her numerous times when they were children growing up in Sleepy Hollow, NY, according to a complaint obtained by theNew York Post. Adam denied the allegations in a statement HollywoodLife received from his lawyer, Andrew Brettler.
