The former Girls Aloud star piled on three stone (19 kilograms) during her pregnancy and was desperate to shift the extra body baggage after giving birth to her son Bobby last year (14).

She dropped two stone (12 kilograms) once she was eating for one again, but she struggled to lose any more weight so turned to meal-replacement brand SlimFast instead - and it was so successful she is now an ambassador for the company.

Walsh says, "SlimFast really works for me and after just a few weeks following the plan I'm back to feeling and looking my best again. I feel on top of the world...

"As a new mum I didn't want to put myself under pressure to snap back into shape. However as Bobby was getting older I found that the last of the baby weight just wasn't shifting. I knew I had to find something that would quickly shift the weight so I could feel at my best again.

"At last, that last half a stone is gone thanks to SlimFast, and I feel like I've got my body and confidence back - as well as my wardrobe!"
