HBO is finalizing a deal for an unscripted comedy pilot from Sex in the City co-producer and writer Amy Harris described as "an attempt to capture the vivacity, sexuality and friendship of women in a big city under the banner of a reality show," sources said.

The Hollywood Reporter says HBO declined comment on the pilot order, a rarity for a network that leans heavily on scripted comedies, dramas and longform projects. But HBO has dabbled in some reality series in recent years, including Family Bonds and Project Greenlight.
