The former Charmed actress recently became engaged to photographer Kurt Iswarienko, and the pair have signed up for a new reality series on US network WEtv.
The weeks leading up to the wedding will be the main focus of the show, which will also include the ceremony itself, according to Entertainment Weekly.
Studio executive John Miller said: "She's insanely compelling. People will see a side of Shannen they never expected to see - unfiltered, honest and vulnerable."
The reality series, yet to be officially titled, will begin airing on the channel in January.
Doherty has been married twice before, to Ashley Hamilton and Rick Salomon. Both marriages ended in divorce in less than a year.
The actress said that she had hopes of getting married for a third time during an interview with People last year.
Doherty had said: "I would consider getting married again because I want kids. That's why I would do it. I believe in marriage as a whole because my parents were married for 43 years, so I have the best example in the world of what marriage can be."
