Blake Lively, Alexis Bledel, America Ferrera and Amber Tamblyn at The Sisterhood of the Travelling Pants 2 premiere

The sisterhood is back! Blake Lively (in Gucci), Alexis Bledel (in Badgley Mischka), America Ferrera (in Brian Reyes) and Amber Tamblyn make a welcome return to our screens next month in the sequel to 2005's successful chick flick The Sisterhood of the Travelling Pants.

The girls were in fine form last night for the world premiere in New York and had a few Gossip Girls (and boys) as well as not-so-ugly Betty's also lending their support by attending. Seems a lot can change in three years - last time round, Blake and America were the two lesser-known actresses, while Amber and Alexis were riding high on their respective small-screen successes.
