Simpson, who was 17 at the time, said she only weighed 115 lbs when she was asked to shed the weight.

Elsewhere in the show, she told fans, 'It feels good to be back on stage in my 40s. I missed all of my 30s, so this really to me, feels like I’m me again. I feel like walking on stage is almost more comfortable than my living room at home, and it’s such a beautiful feeling.'

The mom of three reflected, 'To tell a 17-year-old that is a lot. 

'The second record, I [was told I] needed to have a six-pack, which was definitely not going to happen. I’m just not built that way, you know?'
