A third and final "Sisterhood of the Traveling Pants" movie is allegedly in the works!

Alloy Entertainment is reportedly developing the franchise's fifth and final book, "Sisterhood Everlasting," for a big screen adaptation, according to EW.

The third film would follow the original 2005 movie and its 2008 sequel, both of which starred Alexis Bledel, America Ferrera, Blake Lively, and Amber Tamblyn.

There's no word on whether the girls will reprise their roles, but all four real-life friends have seemed open to the idea in the past.

“The characters are all basically the ages that we are now,” America told EW when the cast was reunited last fall. “I know that the four of us would love [to make another film], and it would be wonderful.”

Liz Garcia will adapt Ann Brashares’ novel for the screen, and Ken Kwapis, who directed the original film, will return to direct once again.

Taking place 10 years after the last events, "Sisterhood Everlasting" finds that the friends have grown apart, so Tibby (Amber) tries to bridge the distance by reuniting the girls for a trip that will change their lives forever.

“The Sisterhood series is one of Alloy’s most cherished properties and we are looking forward to continuing its legacy with Sisterhood Everlasting nearly a decade after the first film was released,” said Alloy Entertainment President Les Morgenstein in a release. “The original film brought together an incredible group of talent who we hope to unite for fans once again.”
