NEW YORK, Oct. 19 (UPI) -- Blake Lively, Amber Tamblyn, Alexis Bledel and America Ferrera still form a sisterhood, nearly 10 years after the foursome starred in Sisterhood of the Traveling Pants.
Lively, Tamblyn and Bledel stepped out together in New York City on Saturday to see Ferrera's off-broadway play, Lips Together, Teeth Apart, just a month after they met up for brunch in Los Angeles.
"Sisterhood dropped by matinee of #lipstogetherteethapart @2STNYC &made my day! I get by w/a lil' help from my girls," Ferrera tweeted Saturday.
"Go America! Supporting our girl in her play, Lips Together, Teeth Apart. #sisterhood," Tamblyn wrote on Instagram.Lively, Tamblyn, Bledel and Ferrera, who have remained friends since their 2005 hit, reunited for a sequel in 2008. Alloy Entertainment said last April that another Sisterhood film is in the pipeline, though they have yet to make any casting announcements.
