Blake Lively's famous friends and costars are speaking out in support since her complaint against 'It Ends with Us' costar Justin Baldoni

Since starring in the 2005 movie "The Sisterhood of the Traveling Pants" and its 2008 sequel, Lively, Ferrera, Tamblyn, and Bledel have remained close friends.

In a joint statement released on Instagram, Ferrera, Tamblyn, and Bledel showed support for Lively.

"As Blake's friends and sisters for over 20 years, we stand with her in solidarity as she fights back against the reported campaign waged to destroy her reputation," the statement reads. "Throughout the filming of 'It Ends with Us,' we saw her summon the courage to ask for a safe workplace for herself and colleagues on set, and we are appalled to read the evidence of a premeditated and vindictive effort that ensued to discredit her voice. Most upsetting is the unabashed exploitation of domestic violence survivors' stories to silence a woman who asked for safety. The hypocrisy is astounding."

"We are struck by the reality that even if a woman is as strong, celebrated, and resourced as our friend Blake, she can face forceful retaliation for daring to ask for a safe working environment," the statement continued. "We are inspired by our sister's courage to stand up for herself and others. For anyone seeking more information or engaging in this important conversation online, please read the full legal complaint in the investigative reporting by Megan Twohey, Mike McIntire, and Julie Tate for the New York Times."

In an Instagram Stories post, the author wrote:

"@blakelively, you have been nothing but honest, kind, supportive and patient since the day we met."

"Thank you for being exactly the human that you are. Never change. Never wilt."

The "Bridesmaids" filmmaker directed Lively in the 2018 whodunit "A Simple Favor," and the two recently wrapped on a sequel.

"I've now made two movies with Blake and all I can say is she's one of the most professional, creative, collaborative, talented and kind people I've ever worked with," Feig wrote on X. "She truly did not deserve any of this smear campaign against her. I think it's awful she was put through this."

Robyn Lively, Blake's half-sister who also starred in "It Ends with Us," posted on Instagram to show her support.

"She is one of the kindest, most honest and loving humans I know. Blake isn't a villain. She's a mama bear to her core, a loving and supportive wife, a sister, a friend, and someone who worked her ass off on a film in abominable working conditions," she wrote.

Sklenar, who starred as Atlas in "It Ends with Us," wrote on his Instagram Stories, "For the love of God read this," linking to The New York Times story that highlighted the lawsuit. He also included a heart emoji next to Blake Lively's handle.

Slate, who plays Allysa in the movie, gave a statement to Today.com supporting her costar.

"As Blake Lively's castmate and friend, I voice my support as she takes action against those reported to have planned and carried out an attack on her reputation," Slate said. "Blake is a leader, loyal friend and a trusted source of emotional support for me and so many who know and love her."

She continued: "What has been revealed about the attack on Blake is terribly dark, disturbing, and wholly threatening. I commend my friend, I admire her bravery, and I stand by her side."

The comic posted on her Instagram Stories the words "I believe Blake."

It's a surprising show of support as Schumer back in 2015 mocked Lively on her show "Inside Amy Schumer."

Levy, who has worked with Lively's husband Ryan Reynolds multiple times, most recently on "Deadpool & Wolverine" (and gave Lively a cameo in the movie), took to his Instagram Stories to support Lively.

"Proud to call @blakelively a friend," he wrote, and linked to the New York Times story.

The Bachelor Nation alum took to TikTok to show support for Lively. He also noted that he received pushback when he tried to warn his listeners about Baldoni on an episode of his podcast "The Viall Files" back in August.

"I'm not here to gloat; I'm honestly just happy that the truth is out about this guy and, more importantly, how wrong ya'll were about Blake," he said.

Ricci posted an Instagram Story in which she shared a quote about misogyny and tagged the writer Rebecca Woolf.

"Re: Blake Lively (and Amber Heard TBH) misogyny exploits the jealousy women feel for each other — specifically when it comes to beautiful women & girls. The fact that 'mean girls' are always beautiful is no coincidence. The ease in which women are manipulated into hating each other (even feminist women) is something no one wants to talk about. This is (yet another!) reminder to question our willingness to burn ANY woman. That includes beautiful, successful women who dare to have a voice."

Olson stars in "It's Always Sunny in Philadelphia" alongside her real-life husband, Rob McElhenney, who co-owns the soccer team Wrexham A.F.C. with Lively's husband, Ryan Reynolds. She posted an Instagram Story supporting Lively, calling her "a kind, lovely, honest and generous person (and an incredible mom) FYI."
