WATCH: Leona Lewis performs spine-tingling cover Robbie Williams 'Angels' to support healthcare workers

Leona Lewis is a name that you may not have heard for a while.

The British singer has stayed relatively quiet since her hits 'Better In Time' and 'Bleeding Love' catapulted her onto the world stage. 

However, in a show of support for British healthcare workers, Lewis belted out a cover of Robbie Williams' Angels which is simply breathtaking. 

“It’s a big song to touch, but I think in this scenario I needed this lyric to convey the message and tribute,” Leona Lewis said.

Since the video was posted a week ago, many fans have been struggling to contain their emotions.

"Tears are rolling down my face" said one, with many others sharing the same fate.
