Kate Bosworth

"Landing in Washington DC to speak at Vital Voices Global Leadership Awards, and I could not be more honored than to participate in such a special event and on #internationalwomensday. Vital Voices was created to make space for women to be heard. The founders knew then what has now become a universal truth: that women are essential to progress in their communities. Our world cannot move forward without their full participation. Today, the organization is the product of the women they have worked with, their insights into leadership and our changing world." – @katebosworth

Lindsay Lohan

"'Women are not created weaker but more generous than men. They are created more beautiful and less fierce, as beauty hates to hurt and harm others. That is why they seem weak to people, but in reality they are not. Angels are the strongest of created beings, and women are closer to the angelic nature than men, as they are readier than men to carry angelic light- – Prophet Mohammed – happy women's day" – @lindsaylohan

Rashida Jones

"Today is International Women's Day. There is an initiative to wear red, not to spend money, not to go to work, to do what you can to remind the world how essential women are. If you can't do any of these things, if your life prohibits you from doing so, don't. If you want to support the initiative in your own way, you can. If you don't care, then keep it moving. I'm done with overly simplistic comments from people who are looking to complain about celebrities and their privilege. I'm aware of my privilege and that doesn't make me care any less. Let's remember that a reality star born into wealth is now President. (Also, a man who bragged about sexually assaulting women) Some of you complaining voted for him. So there is a disconnect. In any event, women all over the world, including this country, are struggling for equality. I stand with them. #internationalwomensday" – @rashidajones
