The 34-year-old star also chats with ET about how life is different now that she has a 3-month-old baby at home.
It's already been a big year for Amber Tamblyn.
Just three months after she and husband David Cross welcomed daughter Marlow into their family, the 34-year-old star was making her directorial debut in New York City, with her famous friends by her side. In addition to her Sisterhood of the Traveling Pants co-stars showing up to the premiere of Paint It Black on Monday night, Tamblyn talked to ET about the support and inspiration she's received from Amy Poehler and Amy Schumer.

In fact, it was Poehler who suggested to Tamblyn that she adapt Paint It Black, which is based on Janet Fitch's 2006 novel of the same name. "Amy [Poehler]'s been a friend of mine for a really long time," she praised the Parks and Recreation star, who showed up to the premiere's after-party. "I give her full credit."
As for Schumer, who also came out to support her at the premiere, Tamblyn gushed, "I really I adore her and she's amazing and she's somebody that fills me with a lot of joy."
She also revealed that they are on a "text chain" with Girls star, Lena Dunham. "We support each other and give each other a lot of love," Tamblyn noted, before quipping that the texts are "mostly just, like, pictures of zits."
Schumer proved how much she has Tamblyn's back when she posted a photo to Instagram from the premiere and bragged about her pal. "Constantly blown away by my brilliant friend @amberrosetamblyn," the comedian wrote. "Her film #paintitblack will stop your heart and light it on fire."
Prior to the premiere, Tamblyn celebrated her first Mother's Day and shared with ET that the weekend included a little bit of work and a stiff drink. "I'm doing a play at the Vineyard Theatre, so I did that," she said of her Sunday. "Then afterwards, I had a big thing of bourbon and then I pumped and dumped."
