Although The Sisterhood of the Traveling Pants, was made way back in 2005, the four co-stars have proven that they are still the best of friends after Blake Lively posted a sweet photo of them together, calling them her "inspiration."
The film is a coming-of-age story about as group of friends who post the same pair of jeans to each other when they spend their first ever summer apart as a way to stay connected, but it looks like the real life bond between the four actresses, Blake, America Ferrera, Alexis Bledel and Amber Tamblyn is just as strong in real life.

Blake is currently promoting her latest film, The Shallows, and opened up about the gruelling training for the role. She told Entertainment Tonight: "I was working out 13 hours a day because shooting was working out. It was neat to be able to do that, and it was neat to have that challenge after having a baby, because you think your body is so different – you think no matter what, it's never totally [going to] be the same."
