On Saturday, Jan. 21, 2017, more than 2 million people all over the world marched for gender equality rights. Many celebrities were right there with them.

After all, female celebrities — no matter how famous they are — will not escape the gender injustices that are likely to arise in our new administration. So they took their place in the crowds alongside fellow activists, loudly echoing their sentiments every step of the way, as per the Women's March mission:

"We stand together in solidarity with our partners and children for the protection of our rights, our safety, our health, and our families - recognizing that our vibrant and diverse communities are the strength of our country."

Some also used their celebrity status to push the message out even further by giving bold, impassioned speeches in front of the masses.

But whether they were in front of a microphone, holding a sign, or sporting a pink pussy hat, their presence among the masses was inspiring. So much of the march was about inclusivity and sharing that purpose with like-minded celebrities reminded people that no one is above that concept.

Here are 27 activist celebrities who marched for the cause.

1. Ashley Judd gave a heart-stopping rendition of Nina Donovan's "Nasty Woman" poem.

2. Elizabeth Gilbert brought an appropriately revised copy of her book, "Eat, Pray, Love."

3. Ariana Grande marched with her female role model — her grandmother.

4. Connie Britton rocked a Planned Parenthood poster in Park City, Utah.

5. Katy Perry made a new feminist friend at the Los Angeles march.

6. Jessica Chastain casually handed out love buttons at the march in Washington, D.C. NBD.

7. Drew Barrymore's daughter Frankie's sign was honest and on point.

8. If anyone messes with Melissa Benoist (aka Supergirl) and her vagina, they'll be very, very sorry.

9. I'd say Brie Larson's fans appreciated her presence among them.

10. America Ferrera's speech at the March on Washington kicked off the day. Watch it here.

11. Ian McKellen marched in London with a poster of Patrick Stewart as Captain Picard. Needless to say, people couldn't get enough of him.

12. Scarlett Johansson's speech on how Planned Parenthood helped during her teen years brought the house down.

13. Gillian Anderson sported a "We the People" poster designed by Shepard Fairey.

14. Mandy Moore paired up with the inimitable Jane Fonda.

15. "Hidden Figures" actress Janelle Monae's speech says it all.

16. Maggie Gyllenhaal and her brother Jake did the Women's March on Washington sibling-style.

17. Amber Tamblyn and Amy Schumer mutually supported women's rights (and NASA).

18. Sometimes there's an actor who was in a movie your protest poster is quoted from, and everything's suddenly right with the world.

19. A highlight from one epic speech by Gloria Steinem.

20. Chelsea Handler, together with Charlize Theron and Mary McCormack, were "loud and proud" at Sundance in Park City, Utah.

21. Nick Offerman wore a pussy hat with pride (as well as some snow).

22. "Orange Is the New Black's" Jackie Cruz showed off major sign skills.

23. And Amy Poehler would not be Amy Poehler without creating a hilariously awkward situation.

24. Comedian Jenny Slate carried a sign for someone who couldn't make it to the march.

25. Alicia Keys took sisterhood selfies.

26. Zendaya was just one more in the over 500,000 person crowd in Washington, D.C.

27. And, finally, the feminist who started #HeForShe did her part for gender equality while hanging with her mom, taking photos of kids, and laughing with strangers who are now friends.

Seeing the icons we look up to marching for what's right is one heck of a reminder that we're far from alone in this fight.

Their presence at these protests makes a difference on many levels, but perhaps the most significant is showing we are all unified under one purpose. And we are going to keep defending each other and every group  marginalized under Trump's administration.

Over the next four years, we will be up against a government that may try to strip us of our human rights at every turn. The more powerful, publicly known voices who stand with us and amplify our frustrations, the harder it will be for them to be ignored.
