Last month, she shared an incredible before and after bikini snap showcasing her incredible weight loss on Instagram.

The image showed two snaps of the star side-by-side, taken a year apart, and showcases the incredible body transformation she’s made over the last 12 months.

In a lengthy caption, the singer revealed that after seeing her before picture, she vowed to rebuild her ‘physical strength’ for the sake of her 22-month-old son Hudson. 

Describing her decision to overhaul her body, Katie explained that her first picture was taken shortly after she returned to the UK following the breakdown of her relationship and at the start of her life as a single mother.

‘Last summer, I was fresh off the boat from an international move, a first time mum, & in the next chapter of rebuilding my life as a single parent & career change. It was this picture that sparked a huge change within me.

‘Everything from the frowned facial expression, hair loss, exhaustion, and yes lastly my body shape that i wasn’t used to nor recognized. I looked at myself in the mirror & cried. Not because I was horrified,but because I didn’t know how I would find the strength or time to do anything to make a positive change. B U T I did!’ 

This isn’t the first time the singer has shared before and after pictures of her image overhaul.
