Opting for a Zara number which clearly showed off her slim waist, Claire looked very chic indeed on ITV's Loose Women.
The singer, 36, has lost a considerable amount of weight recently, and we weren't the only ones to notice how fab she looked on Monday.
Soon enough, praise was pouring in via Twitter with fans saying she looks "amazing", "gorgeous" and congratulating her for slimming down.
Feeling a bit overwhelmed, Claire said: "Thankyou all again for being sooo lovely with your comments. It'll go to head if your not careful xx."
How sweet! Claire totally deserves all the praise.
It's not the first time the star has lost weight, but this time Claire hasn't done it with a fitness DVD in mind.
Instead, the mum-of-two has lost weight to get herself in the best possible shape to try for another baby.
Meanwhile, she's enjoying trying on new clothes and recently shared a snap of herself in some very racy print trousers.
And, you'll be pleased to know that it's not all work and no play for Claire.
She also uploaded a photo of her treat, a gin and tonic, to Instagram. Delicious!
