The blonde singer appears to have lost lots of weight since we saw her last, showing off a slender figure in black skinny trousers and a chic blazer.
Claire was appearing on the Loose Women panel on Tuesday (1 April), where the ladies all removed their make-up in support of the make-up free cancer awareness campaign that has been going viral in recent days.
Tweeting after the show, Claire said it had been fantastic to meet the young woman, Fiona Cunningham, who kickstarted the whole fundraising campaign.
"What an inspiration this young lady is!" said Claire, alongside a picture of Fiona. "Humbled to meet her after raising over £8 million for cancer research
The campaign encourages people to post make-up free selfies of themselves online and make a donation to cancer research. They can then nominate others to do the same.
Meanwhile, today was Claire's first panel appearance on Loose Women and it went down a storm with fans, who took to Twitter to praise her.
One wrote: "You were fab. Hope it's a regular thing. I wish I looked as good with make up as u all looked without!" Another added: "Never realised how beautiful you are without make up. Your man's a lucky guy. And a worthy cause."
A third said: "You did very well today like a duck to water! I watched it for the first time in months well done."
Claire tweeted at the Loose Women ladies: "Thankyou so much for looking after me ladies! Had a great time even with no make up."
Hopefully she'll be back
