American actress Kaitlin Olson expressed her support for Blake Lively following her legal action against Justin Baldoni.

Olson joins others, including Lively's "It Ends with Us" co-stars Brandon Sklenar, Michele Morrone and Jenny Slate, who have supported her since she filed her lawsuit against Baldoni.

Lively's husband, Ryan Reynolds, who co-owns Welsh soccer team Wrexham AFC with Olson's husband, Rob McElhenney, also broke his social media silence recently days after his wife's legal action.

Lively continues to receive support from Hollywood stars following her sexual harassment lawsuit against Baldoni, with the latest coming from Olson.

On Thursday, Olson reposted the Instagram Reel from her Instagram Stories The New York Times.

The column featured Lively's complaint against Baldoni and his alleged smear campaign against her.

Along with reposting the post, Olson added the caption: "@blakelively is a kind, lovely, genuine and generous person (and an amazing mom). FYI."

Olson's message of support came days after Lively's "It Ends with Us" co-star Jenny Slate expressed her determination to stand by her side amid her legal action.

In a statement given to Today.comSlate said, "As a comrade and friend of Blake Lively, I express my support as she takes action against those who are reported to have planned and carried out an attack on her reputation."

Slate also said, "Blake is a leader, a loyal friend, and a trusted source of emotional support for me and the many who know and love her."

The 42-year-old actress described the revelations about Lively's attack as "horribly dark, disturbing and completely menacing".

She concluded: "I commend my friend, I admire her courage and I stand by her."

On Monday, another of Lively's "It Ends with Us" stars, Michele Morrone, took to her Instagram Stories to post an emotional video expressing her support.

Morrone said he's not the type to post such videos, but he feels it's "time to stand up" for Lively, whom he "really" loves.

The Italian actor said that he met Lively on the set of the sequel to "A Simple Favor" and immediately felt that something was wrong. He added: "I felt pain and then when we had a chance to talk, me and her... Blake was in pain."

Morrone shared a link on The New York Times article detailing Lively's legal appeal and asked his followers to read it.

He explained, "So that's why I want to link right here to the New York Times article just so you understand before you comment on what happened. That's all I'm asking. That's what I want you to do."

Before Morrone's announcement, "It Ends with Us" actor Brandon Sklenar and author Colleen Hoover also posted messages of support for Blake Lively.

Sklenar shared on his Instagram stories on Monday The New York Times a link and a message inviting his followers to read the article. He wrote: "For the love of God, read this."

Meanwhile, Hoover took to her Instagram Stories to share a picture of herself and Lively hugging during a screening of the film.

In the caption of the post, Hoover wrote, "@blakelively, from the day we met you have been nothing but honest, kind, supportive and patient."

She concluded: "Thank you for being the man you are. Never change. Never will."

Other celebrities who have given Lively support include "A Simple Favor" director Paul Feig and America Ferrer, Alexis Bledel and Amber Tamblyn, who starred alongside her in "Sisterhood of the Traveling Pants."

The "Deadpool" actor posted a message on his Instagram stories on Dec. 23 asking for support and donations for Sick Kids ahead of Christmas.

He announced that he and Lively would match each donation with $500,000 and described the organization as "a sanctuary for so many children and their parents who are going through the unimaginable."

Reynolds' message did not address Lively's legal situation, but some fans interpreted it as a subtle hint of his support for her.

Lively and Reynolds have been married since 2012 and have four children: daughters James, Inez, Betty and son Olin.
