"Together, women can."

That's the message celebs like Kerry Washington, Eva Longoria, Lena Dunham and Serena Williams are helping Facebook CEO and author Sheryl Sandberg broadcast to the world as part of a brand new arm of her Lean In campaign focused on encouraging women to support and empower one another in the workplace.

"We see all the time women supporting other women. And I think there's a myth out there that women don't, and it's not true," Sheryl told Amy Rohrbach on June 23 edition of "Good Morning America," (via ABC.com).

"We know that women get interrupted more than men. And if you're getting interrupted, of course you should be able to say, 'Hey, I haven't finished,' but that can be hard. Another woman sitting next to you can say, 'Hey, I'd really like to hear what Amy was about to say,'" Sheryl explained, sharing an example of the small ways women can help level the playing field when it comes to gender equality at work.

Other suggestions she made in the segment included giving credit for female colleagues where credit is due and leaving the word "bossy" out of descriptions of little girls, since it's almost never used in reference to little boys, whom she said are "expected to lead."

The celeb-packed PSA that launched this week features equally moving stuff.

"I'm going to try to say this without getting really emotional," says Kerry Washington in the video. "I'm not sure what my life would look like if not for Shonda Rhimes."

Other celebs share similar stories: Emma Watson, whose already made strides in the fight for gender equality through her work with the HeForShe campaign, shouts out Sophia Coppola, whom she says "believed in me and made me believe that I could do more."

Megyn Kelly shares that what moved her most about the past year "was the outpouring of support I got from women," one of two implied references in the PSA to her infamous debate-birthed battle with Donald Trump's misogynistic comments, most of which she lobbed right back at him like a boss.

As the video continues, Lena Dunham gives props to her Lenny newsletter cohort Jenni Konner, and Selena Gomez says simply, "The women I work with are everything."
