Blake Lively took to Instagram on Monday, sharing a snap with her former co-star Amber Tamblyn.
In the photo the, the actresses – bundled in winter gear – smile at the camera looking fresh faced and happy during their mini reunion.
"WHERE are my hands?!?! #SisterWivesOfTheTravelingPants," Lively, 28, captioned the photo.
Tamblyn, 32, who is married to comedian David Cross, also shared her own selfie of the two on Friday.
"#tbt to my sister. Happy new year. I love you," she captioned another smiley photo of the pair.
Expanding their reunion, Tamblyn also shared photos with the other two cast members of the film, Alexis Bledel, 34, and America Ferrera, 31.
"#tbt to right now," Tamblyn captioned the photo with Ferrera. "Love you sister. Happy new year."
If the rumors are true, the ladies will be seeing a lot more of each other. Although there hasn't been much buzz about it, Ferrera said last January that a third installment of the franchise was on the table.
"It's actually very much in the works," she told PEOPLE. "There's a fifth book, and what's wonderful about it is, and the series to begin with, is that it's really raw and honest about friendship and how hard it can be and how it changes as you grow up."
From the looks of it, not much has changed between the cast mates.
