Good question. Another one in the same early 90's big-boobs-on-talk-shows vein I'd like to know about is Chesty Love, but that is another thread.
As for Rocki, actually, as I recall, she appeared on Sally Jessie Raphael twice (once with Chesty Love and Rachel Rocketts? and once on a retrospective show, in her red, white and blue bikini), and on the Richard Bey Show once, in Bey's dumb version of musical chairs.
I recall that when she was on SJR, she mentioned that she was either a bartender or owned a bar somewhere in Illinois--perhaps that is what she wound up doing. I don't believe she posed for many photo shoots. I don't know that for a fact, but I did notice that my own collection has precious few photos of her in it, and Googling doesn't turn up much, either. I think she was primarily a feature dancer rather than a model.
