Singer Claire is known for yo-yo dieting, having been a size 20 at her heaviest and an eight at her thinnest, and she looked A-Mazing during an appearance on ITV1's Lorraine today (14 June).
Showing off her svelte frame in a black and white spotty blouse and black skinny jeans, we admit we had to do a double take!
Speaking to Lorraine about her weight loss, Claire said: "I feel good, I'm really happy. This is the longest I've managed to maintain it and that was always my big problem."
When Lorraine used the phrase "eat less, exercise more" to explain the best way to ditch the pounds, Claire replied: "One hundred per cent, it's not rocket science." She added: "I'm in a really good place."
In 2013, Claire - who has previously said she is "addicted to food" - appeared on Celebrity Big Brother alongside eventual winner Rylan Clark and she began her weight-loss journey soon after.
By January last year, Claire had managed to shed a whopping six stone but admitted to Reveal that keeping it off was tough.
She told us: "I hope I've broken the cycle, but I think I've learned my lesson by saying, 'This time it's for good'.
"There is always a possibility that I could be a size 16 again in a year's time. I'm just taking each day as it comes.
"Starting a diet is always the hardest bit, but it's never easy. It's a challenge and a battle every single day."
Judging by her appearance today, we think she's cracked it! Wow!
