Earlier that day The Keeping Up With The Kardashians star opened up to Kelly about the failure of her marriage to basketball player Kris Humphries.
'It's been a hard couple of months,' she said about the brief marriage and the fallout that happened once the couple split.
'If you really think about it, if this was a business decision and I really made all that money that everyone was claiming that we made off this wedding, and if the wedding was fake and just for TV, I'm a smart businesswoman, I would have stayed married longer,' Kim said.
'I really didn't think following my heart would create this much backlash.'
