Sean Penn -

The actor actually traveled to Ukraine to work on a documentary about the conflict. "Already a brutal mistake of lives taken and hearts broken, and if he doesn't relent, I believe Mr. Putin will have made a most horrible mistake for all of humankind. President Zelensky and the Ukrainian people have risen as historic symbols of courage and principle. Ukraine is the tip of the spear for the democratic embrace of dreams. If we allow it to fight alone, our soul as America is lost," Penn tweeted. His visit prompted Russian officials to put him on the list of names permanently banned from entering Russia.

Ben Stiller -

Ben Stiller, a UNHCR ambassador, decided to make the trip over himself to mark World Refugee Day on June 20. After visiting several areas that were hit hard in the region in the days prior, the actor met with President Volodymyr Zelenskyy in Kyiv and told him almost immediately, "You're my hero." He continued, in a video shared by Bloomberg, "You quit a great acting career for this," and Zelenskyy joked that it wasn't as great as Stiller's. "But what you've done and the way that you've rallied the country, and the world, it's really inspiring," Stiller added. They had a conversation about the media's role in which Stiller also said that it's hard to understand what's going on through videos and photos without actually experiencing it in real life.

In the days prior, Stiller spent time meeting with displaced Ukrainians, speaking with families whose lives have been torn apart by the war and violence, in the hopes of sharing stories of the human impact of war, and to amplify calls for solidarity, reports the UN.

U2's Bono and the Edge held a surprise concert at a subway station turned bomb shelter in the center of Ukrainian capital of Kyiv on May 8. They performed a 40-minute acoustic set for about 100 people, many of whom were soldiers, which included hits like 'Sunday Bloody Sunday,' 'Desire,' and 'With or Without You.' They were also joined by Taras Topolia, a serviceman in the Ukrainian Army and lead singer of popular local band Antytila, for a rendition of 'Stand By Me' but with the lyrics changed to "Stand By Ukraine."  

During the concert, Bono praised Ukraine’s fight for “freedom” and emphasized that their fight was being heard around the world. “The people in Ukraine are not just fighting for your own freedom, you are fighting for all of us who love freedom,” Bono said, according to the Irish Times. “They can take your lives, but they can never take your pride,” the U2 frontman added.

Orlando Bloom -

Orlando Bloom flew to Moldova in his capacity as a UNICEF Goodwill Ambassador. He spent his trip volunteering with Ukrainian mothers and children who had escaped the war by crossing the border into Moldova. Bloom was overwhelmed by what he saw there and wrote a heartfelt essay to share his experience. "As a father, I would do whatever it took to protect my children, yet I could barely begin to comprehend the devastating decisions these mothers were forced to make,” he explained, referring to the lengths many parents had to go to in order to get their children out of Ukraine safely. They fled their homes and the lives they had known to escape the bombing, risking everything to cross the border and reach what they hoped would be safety.

Bloom also shared some important information from UNICEF: “Together, with the 2.5 million children internally displaced inside Ukraine, [the war has led to] one of the fastest large-scale displacements of children since World War II." He reflected on the fear and trauma that was changing the lives of so many children, and wondered what it would be like for his own kids "to suffer the pain and grief of losing their homes and everything they’ve ever known in a senseless instant.” Bloom finished his essay by recalling a small act of kindness from a local Moldovan man who came to bring toys to the refugee children, and hoped that small gestures such as this would help them make it through the crisis.

Pink Floyd -

The legendary English rock band Pink Floyd has reunited to create new music for the first time in almost 30 years to raise money for the people of Ukraine. Core band members David Gilmour and Nick Mason have teamed up with Ukrainian rockstar Andriy Khlyvnyuk for their song, 'Hey Hey Rise Up.' (Roger Waters, who left Pink Floyd in the 1980s, is not involved.) Gilmour was inspired by a video of Khlyvnyuk singing a patriotic Ukrainian song outside of Kyiv's St. Sophia Cathedral and decided to sample it for a new track, with Khlyvnyuk's blessing. Khlyvnyuk was touring the US when the invasion occurred and immediately flew back to his home country to join the territorial defense efforts. He was in hospital recovering from a shrapnel injury when he got the call from David Gilmour. The song was released on Friday, April 8, and all of the proceeds will go to the Ukraine Humanitarian Relief Fund.

She and her husband posted a video to social media on March 3 about the conflict, and Kunis stated that she's "never been more proud to be a Ukrainian." She condemned Russia's actions, saying, "The events that have unfolded in Ukraine are devastating. There is no place in this world for this kind of unjust attack on humanity." The couple shared a GoFundMe page to raise money for aid in Ukraine, and just two weeks later, they posted on Instagram to say that over 65,000 people had donated and helped them reach their goal of US$30 million. "We are overwhelmed with gratitude for the support," Kunis continued, "While this is far from a solve of the problem, our collective effort will provide a softer landing for so many people as they forge ahead into their future of uncertainty."

I'm praying for my family and friends there and everyone who's fighting. I wish you had more support and I wish I was there fighting with you!

I am torn in two as I watch the horror unfolding, the country being destroyed, families being displaced, their whole life lying in charred fragments around them," Jovovich wrote on Instagram. "I remember the war in my father's homeland of former Yugoslavia and the stories my family tells of the trauma and terror they experienced. War. Always war. Leaders who cannot bring peace. The never ending juggernaut of imperialism. And always, the people pay in bloodshed and tears," she added.

"I do know what it's like to grow up after a war, in an occupied country, and I know that in war and its aftermath, no one wins. Everyone suffers. War has a way of breaking the winners along with the losers. I have Ukrainian friends and fans and I have Russian friends and fans. As far as I can tell, none of them want this. I hope sanity will eventually prevail and end this unnecessary war before too many lives are broken. In the meantime, I stand with the people of Ukraine.

Annie Lennox -

On February 23, a day before the Russian invasion, the singer shared her thoughts on the matter: "Now that the tanks, soldiers and war machinery are on the brink of entering Ukraine…what now? The hell that 'warfare' unleashes? A frenzy of blood letting.. Crushing of flesh and bones.. The collective trauma of suffering of pain, grief, anguish and despair for innocent men, women and children? What kind of 'price' must ordinary people pay for the nightmarish madness and brutality of 'invasion' and 'warfare'? Or is this just an elaborate hoax? A scare tactic? A threat? Apologies for this dark reflection, but I've had the privilege of living in a 'peaceful' context since I was born – a decade after the end of WW2 – 67 years in total. I don't take this for granted in any way and therefore find the notion of 'war' to be unacceptable repugnant barbarism. Sorry friendsI just had to express this."

Val Chmerkovskiy -

The Ukrainian-born dancer, best known for his work in 'Dancing with the Stars' and brother of Maksim Chmerkovskiy, opened up about his past and asked for the Russian people to stand up to Putin. "My parents fled this country for this exact reason. Not because it wasn't good to them, but because their kids would see war eventually. It's a cruel irony that 28 years later my brother [Maksim] is in a bombshelter in Kiev. If they hadn't left I would be on the front lines defending my home right now. And the most heartbreaking thing of all I would be either killing or dying at the hands of my fellow brothers. The Russian people don't want this!! We stood by each others side. We loved and celebrated one another. I speak Russian yes but make no mistake about it, I am a proud Ukranian and now the world will finally know the difference. Slava Ukraini all day every day! And to all my Russian friends this might be the best and only time t stand up to your dictator."
