NEW YORK (AP) – A cross-generational group of stars from film, TV, sports and music – including Bruce Springsteen, Hugh Jackman, Elton John, Jon Bon Jovi, Jonas Brothers and Billie Eilish – have signed up for a social media campaign to show support for Ukraine .

The social media rally hosted by Global Citizens on Friday urged governments, institutions, companies and individuals to help fund humanitarian efforts in Ukraine and other regions of the world. Celebrities were asked to use their social media accounts to publicize the effort, using the hashtag #StandUpForUkraine.

Springsteen posted a video on social media Friday to show his support: “Refugees in Ukraine and around the world need our help now,” he said. “Everyone has the right to safe and humane living conditions.” Barbra Streisand tweeted a link to Global Citizen and wrote: “I support and hope you do too.”

The roster also included The Weeknd, Alanis Morissette, Alejandro Sanz, Angelique Kidjo, Annie Lennox, Billy Joel, Celine Dion, Chris Isaak, Chris Rock, Demi Lovato, FINNEAS, Garth Brooks and Trisha Yearwood, Green Day, Carole King, Jon Batiste , Juanes, Kacey Musgraves, Katy Perry, Leon Bridges, Luke Combs, Madonna, Miley Cyrus, Pearl Jam, Pharrell Williams, Priyanka Chopra Jonas, Radiohead, Red Hot Chili Peppers, Shaquille O’Neal, Stevie Nicks, Stevie Wonder, Weezer, 5 Seconds of Summer, Dave Matthews, Radiohead, Miley Cyrus, Tame Impala, U2 and Usher.

Celine Dion took to Instagram to upload a support video with captions in English and French saying: “I call on world leaders to help all those who have been forced to leave their homes.” Ellen DeGeneres in her own video urges world leaders to “do the right thing and donate the billions they need.”

This campaign is also followed by players for the Sacramento Kings NBA, Toronto Raptor and the Memphis Grizzlies, the band Metallica, Billy Porter, Julian Lennon, Adam Lambert, Luis Fonsi, MÃ¥neskin, Padma Lakshmi, Weezer and Rita Ora.

Lenny Kravitz posted a photo of himself on Twitter holding a sign that read in part, “Let love rule, not war.” Ozzy Osbourne and his wife, Sharon, posted a video of support and plea: “We ask everyone who is seeing this to strengthen this call.”

The campaign comes a day before Saturday’s pledge conference co-hosted by European Commission President Ursula Von Der Leyen and Canadian Prime Minister Justin Trudeau.
