Actress Melanie Watson
Dead at 57 …
Played Kathy on ‘Diff’rent Strokes’

Melanie Watson Bernhardt — an actress known for her role on the hit TV show “Diff’rent Strokes” — has died … TMZ has learned.

We’re told Melanie — who was born with osteogenesis imperfecta, a disease where a person’s bones fracture easily — had been in the hospital after suffering some issues with bleeding, where she quickly deteriorated.
Robert says the doctors did their best to help her … but, in reality, she was fortunate to live as long as she did with her condition. he adds he will always think of his sister a great deal.

A 1982 episode was memorably named after her character … in which she and Gary Coleman‘s character, Arnold, argued when he tried to convince her to walk without crutches.
