On Tuesday, Bridges said he was "deeply saddened" by Bain's death, and noted that he'd been looking forward to celebrating the actor's 90th birthday next month.

"In addition to being a positive and supportive father figure both on and off-screen, Conrad was well-loved and made going to work each day enjoyable for all of us," Bridges said in a statement to E! News. "He will be missed, but never forgotten."

Bridges, Dana Plato and Gary Coleman, the series' breakout star, each endured much-noted off-screen troubles during and not long after Diff'rent Strokes' run. Plato committed suicide at age 34 in 1999. Coleman died of a brain hemorrhage in 2010. He was 42.
