How did Stevie get her name?

[kgbmac]

I've heard that here real name is Stephanie, but as a baby she couldn't pronounce it and would say TD instead. I guess that eventually turned into Stevie. I looked but could not find a thread for this question, so forgive me if it's already been discussed.

Does anyone have the real story about how she came to be know as Stevie?
