A host of big names have joined forces to help support those affected by the Orlando shooting. Britney Spears, Jennifer Lopez, among others feature on new charity single Hands, which was written by Justin Tranter, the man behind Justin Bieber's Sorry, and Julia Michaels.

On 12 June, lone gunman Omar Mateen stormed Florida LGBT nightclub Pulse and opened fire. A total of 49 people died in the incident which has been described as the worst mass shooting in US history.

Explaining how he came up with the name, Tranter revealed that in the wake of the atrocities he volunteered at a local LGBT community centre."Like the rest of the world I woke up to the news that morning and was horrified and sad and scared," the long-standing LGBT activist told Billboard magazine. "I called them and said, 'If I fly up is there something for me to help with?" They say, 'We need as many hands as we can possibly get.'"

Mary J Blige, Selena Gomez, Jason Derulo, Gwen Stefani and Meghan Trainor, Pink, Halsey, Imagine Dragons, Juanes, Adam Lambert, the Trans Chorus of Los Angeles, Kacey Musgraves, MNEK, Prince Royce, RuPaul and Troye Sivan also appear on the charity single, which features the lines: "They can hurt or they can heal/ They can give back or they can steal/ They can break the world or they can change it too."

Although a release date has yet to be announced, Hands is available to download on iTunes. All proceeds are expected to go towards helping families with medical care, counselling and will also be used for educational purposes.

Meanwhile, Lopez is going that extra mile by also teaming up with Broadway star Lin-Manuel Miranda to create another charity track entitled Love Make the World Go Round. The songstress shared a snippet of the song - which will help benefit the Somos Orlando campaign organised by local community leaders in Orlando - on her Twitter page.
