The show will follow the launch of a new version of The Pussycat Dolls, with American Idol's Nigel Lythgoe acting as main producer.
Kardashian agreed to work on the programme because Lythgoe is "the best in the business".
A source close to production on the show told TMZ that the new hopefuls are "10 times better than the original group".
The Pussycat Dolls' former lineup, including Nicole Scherzinger, disbanded last year in order to pursue solo careers.
Their co-founder Robin Antin had previously spoken about hopes of rebooting the group with an entirely new lineup.
