I'll admit it: I'm a Sisterhood of the Traveling Pants fan. It all started six years ago when I was a camp counselor and all of my campers were reading a book in the series. Wanting to be "cool" and know what they were talking about, I borrowed their books and read each one.

Maybe it was the fact that it was summer and the books follow the girls through four different summers. Or maybe it was because I enjoy a good story about real female friendship. Either way, I fell in love with the stories of Tibby, Bridget, Carmen and Lena.

When the first movie came out, my sister and I rushed to the theater, and I vividly remember us tearing up at the end of the film. When the second movie came out, things were a bit different. I was working and saw the movie with a few other critics at a screening. It was different than going with my sister, but I still teared up during the sequel. Luckily none of the other critics saw me!

I also interviewed the cast of Sisterhood of the Traveling Pants 2, which made me realize just how much fun the actresses--America Ferrera, Amber Tamblyn, Alexis Bledel and Blake Lively--have together. Their rapport with each other makes the movie come to life, as you realize that their friendship is in real life and reel life.

And that's why you need to check out the Sisterhood of the Traveling Pants 2 DVD. Along with the deleted scenes, the "Jump Off a Cliff" featurette and the gag reel will have you smiling the whole time. Who doesn't love to know that the cast had as much fun making the movie as you did watching it?
