Yes the child star of "family " from 1977! buuut 1979 on she was in one box office flop after another!
I had a huge crush on her for years when I was a kid. I read recently that she has bipolar disorder...so that really messed up her career. She was in a successful tv series a few years back, but pressure seems to exacerbate bipolar illness, and she had to quit it. Of course I had to get the dolly, er I mean action figure, years back. And, she is rumoured to be gay...my Gaydar must have worked even way back then .
