The life of the Duchess of Cambridge's sister will be explored in the one-hour programme called Crazy About Pippa, the network has announced.
The show, which airs next month, will feature insight from "those closest to Pippa" who will discuss her life and work.
Middleton became a household name after serving as Maid of Honour for her sister Kate at her wedding to Prince William at Westminster Abbey in April.
The 27-year-old was recently featured on the cover of Tatler magazine, following in the footsteps of the Duchess of Cambridge who was chosen as the cover star back in February to celebrate the royal engagement.
Crazy About Pippa airs Tuesday, August 9 at 9pm ET on TLC.
