The Depends Lady- Who Knew?

I had a great conversation with my grandma. It went something like this:

(we were discussing an old movie directed by Dick Powell, who was married to June Allyson)
Grandma: I hate June Allyson
Me: Oh really, hate?
Grandma: I hate her for what she did to Dick Powell. Dick Powell was the love of my life. I just read Jerry Lewis' book, and June Allyson was in bed with Dean Martin for two weeks.
Me: Where was Dick?
Grandma: I don't know, probably filming a movie. (she tells a long story about how they would see movies when she was a young girl- a guy would come to town with his projector every few weeks and set it up in a hall. She would watch Dick Powell in the old musicals.)
Me: She was in bed with Jerry Lewis AND Dean Martin?
Grandma: (frustrated that I don't understand) No. She was just with Dean, Jerry was with someone else.
Grandma: And when Dick died, and everyone called him Dick, she came out and said "Oh Richard..." (apparently my grandma found this to be phony)
Me: Well June Allyson died a couple years ago.
Grandma: Good. I'm glad she's dead.

This is from, what? 60 years ago?!?!
