The former "Beverly Hills, 902010" actress is pairing up with WEtv for an unscripted show that will televise her nuptials to fiance, celebrity photographer Kurt Iswarienko, Entertainment Weekly reports.
In addition to the ceremony, the untitled project will chronicle the wedding planning and Doherty's dress shopping.
Cameras will also reportedly follow the 40-year-old as she renovates her home and peruses her acting career.
"People will see a side of Shannen they never expected to see," WEtv executive John Miller tells EW. "She's insanely compelling."
The show is scheduled for a January premiere, with the season finale featuring the couple's wedding.
It will be the third trip down the aisle for Doherty, who also starred in "Charmed" and "North Shore." She was previously married to Ashley Hamilton (from 1993-1994) and Rick Salomo (2003-2004).
