"My favorite girls came through last night. Love them," Tamblyn, who played Tibby Tomko-Rollins in "Sisterhood," wrote on Instagram.
Ferrera, who portrayed Carmen Lowell, shared a group photo with Tamblyn, Lively and Bledel. She, Tamblyn and Lively all wore black, while Bledel stunned in a colorful, floral-print dress.
"Can you see my heart bursting out of my body? I love being with my sisters especially when it's to celebrate," Ferrera captioned the picture.
"@amberrosetamblyn directed her stunning first film, Paint It Black, which comes out this Friday!" she added. "The Sisterhood came out last night to celebrate her enormous talents. We are beyond proud and glowing for her."
