Marquardt confirmed the new project at Star magazine's Young Hot Hollywood party, telling E! News that she was filming the show with her new boyfriend, director Nicolas Carpenter.
The pilot will shoot in April, she added, and it will cover Marquardt's life after moving out of the Playboy mansion, where she lived when she starred on "The Girls Next Door" and was one of Playboy founder Hugh Hefner's girlfriends. It will also involve her relationship with Carpenter.
Marquardt's "Girls Next Door" co-stars, Kendra Wilkinson and Holly Madison, also have their own reality shows.
