Singer Leona Lewis' rendition of Robbie Williams "Angels" left her fans emotional.

The former "X Factor" winner has released the cover in aid of the NHS during their battle against the coronavirus pandemic, reports metro.co.uk.

During a show, the 35-year-old singer sang to a new version of the song.

"It's a big song to touch, but I think in this scenario I needed this lyric to convey the message and tribute," she said.

"It's something I have grown up with and I've always wanted to do it. So, I thought this could be an amazing way to get the message across."

After the "Bleeding love" hitmaker performed the track, fans were quick to take to Twitter where they revealed they were crying at the "beautiful" rendition.
