Britney Spears, Gwen Stefani, Jennifer Lopez and more team up on song for Orlando victims

More than two dozen singers have teamed up on a recording to benefit those affected by the tragic shootings at Pulse Nightclub in Orlando. Britney Spears, Jennifer Lopez and Gwen Stefani are just a few of the A-list artists to lend their voices to the moving tracked simply titled "Hands."

Songwriter Justin Tranter revealed to Billboard that he wrote the song directly following the tragedy, which saw 49 people lose their lives and more than 50 injured in what is now the U.S.'s deadliest mass shooting. The 36-year-old, who has penned numerous hits including Justin Bieber's "Sorry," has been an active member and vocal supporter of the LGBT community since he came out at the age of 14. "Like the rest of the world I woke up to the news that morning and was horrified and sad and scared," he said.

Proceeds from the single, which is available now on iTunes, will be distributed to victims and their families through Equality Florida Pulse Victims Fund, the GLBT Community Center of Central Florida and GLAAD.

Justin was on tour with Selena Gomez when he learned of the shootings on June 12. He quickly reached out to his friends in the business, who didn't hesitate to hop in the studio to record their vocals.

"We assigned everybody what we thought would be the best part for their voice," said Justin, adding that it was an international effort. "Mary J. Blige recorded in New Orleans. Britney Spears in Thousand Oaks, I think. Pink in Santa Barbara. Adam Lambert was in Luxembourg. Everyone just got it done."

Other artists featured on the track include: Meghan Trainor, Imagine Dragons, Jussie Smollett, RuPaul, Mary Lambert and Jason Derulo.
