... at least that's the impression they're leaving. I saw an interview with Alison Arngrim where she talked about how she bonded with Melissa Gilbert, but MSA had a "prom queen" attitude and they were never close.
Didn't think much of it till I was at the library today and they had Melissa Gilbert's autobiography, PRAIRIE TALE, on display. I snapped it up to see what she had to say about the other Melissa, and it was even more dismissive of MSA.
Gilbert said they didn't have any common ground, then dropped the topic. Later in the book she mentions Alison Arngrim joining the cast and said she pulled her aside to tell her "Everybody here is really nice, except one person who is really mean." (No names mentioned.)
The last mention of MSA comes later, when Melissa Sue had to be 15 or 16 and Gilbert gets a whole meow-y paragraph about how much more "sophisticated" Melissa Sue was -- smoking cigarettes and drinking Tab (!) between takes. "Later she would go on to date Frank Sinatra Jr.," she mentions dismissively, and that's it for Melissa Sue.
So: was Melissa Sue Anderson really the Little Cunt on the Prairie, or were Melissa Gilbert and Alison Arngrim ganging up on her, Mean Girls style?
