Miley Cyrus and boyfriend Cody Simpson have delivered 120 tacos to hospital workers tackling the coronavirus crisis in the US.

The 'Wrecking Ball' singer served up the pre-prepared meals from a local restaurant in individual bags marked with the handwritten message: "Thank you for your support & love. Stay strong!!!"

Simpson uploaded pictures of the delivery to his Instagram account, telling fans: "Tacos for the incredible healthcare workers at our local hospital!

"So grateful for these true legends of our time dedicating their lives to battling this pandemic. Show some love to yours in your community!"

The US has the most recorded cases of coronavirus of any country in the world, with President Donald Trump yesterday warning the public to expect "much death" in the coming weeks.
