The 'Girls' star also commented on her and Jack Antonoff's recent split.
Lena Dunham is addressing how much of a hand she had in the forming of Time's Up.
The Girls star's participation in the anti-harassment initiative was called into question after Westworld star Tessa Thompson replied to a comment made to a photo she posted -- and later deleted -- of Michelle Williams, Reese Witherspoon, Rashida Jones, Tracee Ellis Ross, Emma Stone and Dunham pledging their support for the initiative.
The commenter didn't seem pleased with Dunham being featured in the image and called out the fact that she initially defended Girls writer Murray Miller after he was accused of sexual assault. Thompson responded to the remark by claiming that "Lena was not anywhere present in our group during the countless hours of work for the last two months."
"We hosted an open house for the actresses for red carpet messaging and Lena presence was a surprise to us all," she added.
Thompson later clarified her response, admitting that she "sometimes lacks finesse in navigating social media."
"I, in no way, want to diminish Lena Dunham and her work, her voice, and her importance. We have spoken and she knows my heart," the 34-year-old actress wrote. "I regret that my words were misinterpreted to distract from the most important thing: The Time’s Up campaign is for everyone, in all capacities, contributions big and small."
On Instagram Live, Dunham also seemed to responded to the recent criticism. "When you've had this job for as long as I have, which is seven or eight years now, and you've caused some mayhem at times, the internet doesn't necessarily have the same power it used to," she said. "I just feel so lucky that I've gotten to be a part of so many amazing moments and movements in my career. I feel really at peace with the fact that there are moments where you're the hero, moments where you're the villain and moments where you're magic and moments where you're less magic. It's a journey that has strengthened me in ways that are really, really powerful."
Dunham also made headlines this week when she announced her split from Jack Antonoff after five years of dating. While on Instagram live, the 2013 Golden Globe winner revealed that she still wears the ring that the 33-year-old musician gave to her.
"I'll always wear [it] because love is a really cool, eternal powerful, eternal thing," she said. "It doesn't have to be defined the way we, in Western culture, define it -- as beginning and ends. Things can be, 'You're a drop of water and you reenter the ocean.'"
Dunham added, "I really love you all. I'm really thankful for the support. I'm really thankful for the love."
The 31-year-old writer-actress also posted a telling quote following her breakup, which reads: "Starting over is the beautiful moment you choose for yourself."
She captioned the message: "Forever love."
