The 38-year-old is launching the collection for retailer Next and she revealed she has worked with them before.
Speaking to UK newspaper Sunday Mirror, she said: 'I used to work there years ago. So the range is a dream come true. I never thought all those years ago that I'd one day be designing for Next.
'I've worked hard on it, too. I'm not just lending my name. I've gone out, sourced all the fabrics, made the designs with a team and I'm modelling in the campaign too.
'The range is great. I want it to be affordable and, having worn it all myself, I know it's a good product and I'm proud of it.'
