Alloy Entertainment is developing "Sisterhood Everlasting," a film adaptation of the fifth and final novel in Ann Brashares' 'Sisterhood Of The Traveling Pants' series. 'Everlasting' would mark the third film in the series and picks up ten years later after the Sisterhood friends have grown apart. Tibby tries to bridge the distance by reuniting the girls for a trip that will change their lives forever. Ken Kwapis, who helmed the first film in 2005, will return for the third while Liz Garcia ("The Lifeguard, "Dawson's Creek") will adapt the script. Whether stars Blake Lively, Alexis Bledel, America Ferrara and Amber Tamblyn will return - we'll see. Source: Deadline
