America Ferrera has shared a playful snap from a meet-up with her co-stars Blake Lively, Amber Tamblyn and Alexis Bledel, reported Digital Spy.
Lively also posted a photo from the reunion with the caption "#sisterhusbands", while Tamblyn shared Ferrera's post with a poignant message: "Needed my girls today. The world is a crazy place. Hold onto the ones you love. And pick their nose."
The stars have shared their reunions publicly before, going for brunch and supporting Ferrera at her play in 2014.
"There's a strong chance there might be a third. But it would have to be something that really made sense. If you wait this long to do a third movie, it needs to honour the story and the legacy."
Last year, Ferrera said that a third movie was in the works, and it could be based on the fifth and final novel in Ann Brashares's series, Sisterhood Everlasting.
"The Sisterhood of the Traveling Pants" was released in 2005 and was followed by a sequel in 2008.
