Scott Baio is on the defensive about the controversial statements he made following the death of his Happy Days co-star Erin Moran earlier this week. Moran died on Saturday at the age of 56. Officials tell ET that her death was likely due to complications from Stage 4 cancer. However, before the actress' cause of death had been announced, Baio appeared on The Bernie & Sid Show, where he insinuated that the actress died as a result of past substance abuse issues. "For me, you do drugs or drink, you're gonna die," Baio said during the radio interview.
