The trio smiled sweetly as they posed for photos. Bledel rocked a bright, colorful pattered dress, while Tamblyn and Lively opted for toned-down black and white ensembles.

While co-star America Ferrera didn't make an appearance on the press line, she did turn out to support Tamblyn on her big night, and was spotted hanging with her Traveling Pants comrades at the Paint It Black after-party.

Paint It Black
-- a dark drama that explores the pain of loss, suicide, emotional imbalance, healing and destructive relationships -- marks the 34-year-old filmmaker's first time stepping behind the camera.

Tamblyn -- who also recently became a new mom when she and husband David Cross welcomed their first child, daughter Marlow, in February -- opened up to ET about the experience of directing her first feature film.

"I wanted to be able to make something where I could live or die by either failing or succeeding from that experience, so I wanted to make a film that felt daring and felt different than a lot of movies that we see today," she shared. "And if I failed with that, than at least I failed on my own… Ultimately, I just I felt really, really strong about this movie and about the script."
