We're used to seeing Katherine Jenkins dolled up to the nines, with fluttery false eyelashes, lots of bronzer and red lips (see below). But the Welsh soprano joined thousands of other people tweeting 'no makeup selfies' on Thursday in a bid to raise money for cancer charities.
And, while we've never seen her so stripped back, we weren't at all surprised to find that she looked, well, incredible without the war paint.
She posted her pic to her Instagram page, writing: "Hope you're all doing your no make up selfies for #cancerresearch Text 'beat' to 70007 to donate £3 to cancer research #NoMakeUp #NoFilter."
The flurry of no makeup selfies has helped Cancer Research UK raise a whopping £1 million in 24 hours.
Women have been uploading pics of themselves with the hashtag #nomakeupselfie, nominating others to do the same and then donating money to cancer charities.
According to ITV News, a spokeswoman for the charity said on Thursday: "We've had 800,000 text donations since yesterday which has raised more than £1million. It is an unprecedented amount compared to what we would receive normally. It's been great that people are taking the action to donate."
