MTV announced in February that it would not air Conrad's Hills follow-up because the show wasn't a good fit with the cable channel's brand.
Conrad has now opened up about MTV's decision to axe her solo reality series, telling Lucky magazine that she "never wanted to end up in entertainment" and only agreed to film her own reality show in order to promote her fashion lines.
"It's easier to launch the line without MTV," she insisted. "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 also explained that she wasn't comfortable trying to "compete" with some of MTV's more controversial programmes.
"It didn't feel like a perfect fit… 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?"
Aside from work with Paper Crown and LC, Conrad has also signed a three-book deal with publisher HarperCollins and launched her own beauty website.
