Sisterhood of the Traveling pants sequel

I read a few weeks ago in a trash magazine(Star, People or Us which I only read when I fly on airplanes) that they have started making the sequeal to the Sisterhood of the traveling pants. It will have all the same actresses in it and it will focus on things that took place in the last book. So everyone keep your eyes open next summer. I do have to say that I am hoping that some time in the future that she takes the time to write another book for this series. I personally think there were a few cliff hangers in the last book.
