She did say 54 I'm pretty sure...her bio age was maybe 10 years older. I know I did some math to figure out how old she was when she had the boy and it seemed to be in her 40's .
I found it very amusing in an ironic way that Jill didn't want to do the dancing stuff "because she wasn't good at it", didn't want the camera on her. If any of her "victims" had heard her say that can you imagine their response? Suck it up, Jillian! Its good for you to learn to dance!
