Leanna Lovelace, or Leanne or Leosha, began modeling older than most (she looked to be late 30's or early 40's to me but I'm not sure) in 1989. She modeled and was a feature dancer until 1994 when she retired. The rumor I read in two different places is she was drunk and leaned against a hot stove. Her boob caught on fire (huh?) and she had to retire. I think she is from Indiana.
Her breasts continued to grow during her career because of the string type implants she had. The smallest size I saw her listed at was 95FFF and the largest 102JJJ.
