And today the mum-of-one has been braving the media at The Trafalgar Hotel in central London, showing off her new figure in a hot pink bikini.
Promoting Trim Secrets - a pill based supplement - Chanelle posed in a bikini, high heels, and long line cardigan on top of the rooftop bar.
Chanelle recently spoke out about her three stone weight gain last year due to an 'addiction' to food, and her decision to shape up when she saw pictures of herself on the beach in Tenerife.
At the photocall this morning, the former glamour model posed next to a life size cut out of herself from last year.
She said: 'Food can be an abused substance, especially carbs and processed foods. It's addictive, especially when you're depressed.'
'Some people take drugs to get a high - it's the same for me with food.'
The star added that even when she was a size 4, she never felt comfortable with her shape, and had an unhealthy attitude to diet and weight loss.
But this time the star insists she has worked hard to get her body back into shape in a healthy way - exercising and eating well.
