‘I just ate a bag of Cheetos in the back. I do think that writing down what we eat is important to keep [ourselves] in check,’ she continued.
‘When you’re pregnant, I gain a lot, I mean, a lot, she told HSN.
‘I didn’t expect to gain as much with my third. I thought I’d learned my lesson, but apparently that’s just the way God made me, very hungry and pregnant.’
