Erin Moran, R.I.P.

TMZ is reporting that actress Erin Moran has passed away at the age of 56. No cause of death has been given as of this writing.

Moran was best known for playing Joanie Cunningham on Happy Days and its short-lived spinoff Joanie Loves Chachi. Her post-Happy Days life wasn't a happy one mired in problems with alcohol and drugs, health issues, money troubles and even homelessness.
