The 42-year-old launched an intensive fitness regime following the birth of twins Monroe and Moroccan with husband Nick Cannon in April, and has so far lost 70lbs.
But at the peak of her pregnancy weight, she admitted that she couldn't bring herself to let Nick see her naked.
'I had a towel on in the tub,' she told Gayle King. 'I'm not lying, I promise you! You think I would let Nick see me looking rancid like that?'
And she also buried her head in the sand when it came to getting on the scales.
'I didn't want to know [my weight], because why would I want to feel that bad?' she explained. 'I know it was a number that I never want to see again.'
'I had, like, no bones for a while,' she said touching her collarbone. 'It's important to me to feel my bones!'
But she knows that her weight gain came down to eating large portions of 'soul food' and Italian meals.
'Maybe the portions weren't what they should've been,' she said. 'Even as a pregnant woman you kind of have control over it, but you don't feel like it when you're pregnant.
'I'm also 5'9' and I'm not a petite girl.'
