Lady Gaga announced an all-star benefit concert to raise funds for charities and healthcare professionals battling the coronavirus.
The Oscar-winning pop star also revealed that she and the Global Citizen charity have already raised $ 35 million (£ 28 million) for the World Health Organization.
The Gaga event, which she helped organize with Global Citizen, is called the One World: Together at Home concert, and will see stars perform from their homes. The funds raised by the event will support the COVID-19 Response Fund, funded by the United Nations Foundation, which will finance essential PPE, supplies and test kits worldwide.

“We celebrate and highlight the unique and kind world community that is being created right now. We want to celebrate and encourage the power of the human spirit. “
