The mum-of-two took to social media to share a selfie where she looks visibly slimmer on her face, three months after welcoming her second son.
Fans were quick to notice the change, and took to the comments section to gush about how great she looks.
One said: 'I can't believe how much weight you have lost off your face @chanellehayes well done!! 😘'
Another said: 'You look knockout love. Xxx', while a third added: 'You are so beautiful Chanelle. One of the most stunningly gorgeous women out there xxx.'
She's previously discussed her weight - after going from a size 8 to a size 18 in recent years - and said she wanted to slim down ahead of her birthday in November, but then found she was expecting her second child.
'Before I found out I was pregnant my plan was to get down to a size 10 by my 30th birthday in November. That's not going to happen now, but I want to lose weight', she told Closer magazine.
'Since having Frankie I'm more wobbly, I've got stretch marks on my stomach and my boobs are flat - empty Z cups!'
The impressive photo comes only a few weeks after the mum revealed that her partner Ryan had 'walked out' on her.
Chanelle has had a tough time since splitting from her partner Ryan
Chanelle and PE teacher Ryan were together for eighteen months, and announced they were expecting their first child together in March.
In August, the pair took to social media to announce that their little one had arrived.
Things took a turn when the 29-year-old revealed on Twitter that they had split, writing: 'When @RyanJOates drops your child off and you basically beg him to sort your family out but he tells you his family&friends have told him he should have left me even sooner than he did! What a lovely bunch of people.
'We've not split up, he has walked out on me. Nothing mutual about it'.
