The channel was due to follow her as she launched her new clothing line, Paper Crown, in February, but rejected her pilot, stating that the 'subject matter was too high brow'.
And the 25-year-old said that looking back it was the best thing for her.
'It didn't feel like a perfect fit,' she told Lucky magazine. 'It's difficult to compete with all the Jersey Shore-type shows out there. Besides, there weren't any scenes of me getting drunk or fighting, so what's the point?
'It's easier to launch the line without MTV. A lot of people in fashion don't want to be linked with anything that has to do with reality TV. Showrooms were turning us down.'
The former Hills star added that fame was never her dream.
'I never wanted to end up in entertainment - that wasn't the goal,' she said.
'I was doing the show to end up in fashion. But I'm totally aware that without The Hills, I wouldn't be where I am.'
