Roseanne Barr wants to make one thing clear: She's not dead. However, her iconic TV character, Roseanne Conner, the center of the now-canceled Roseanne, is indeed dead. The character was killed off between the Roseanne finale and The Conners premiere. She died from an opioid overdose. Her family originally suspected it was a heart attack until her addiction came to light. Barr, whose show was canceled after a racist tweet aimed at Valerie Jarrett, returned to Twitter the night The Conners premiered and also released a statement with Rabbi Shmuley Boteach about the new show's debut.
