Jessica Simpson is expanding her business empire and has now added a fine jewellery line to her ever-growing fashion company. 

The singer, actress and designer - more commonly known as a triple threat - will launch a "fine jewellery collection with an emphasis on diamonds" in October as Firestar Diamond's first celebrity license. 

Speaking to Women's Wear Daily, Simpson explained that "jewelry is such personal expression of style and taste. This collection has allowed me to create pieces that truly reflect who I am, and that can become a keepsake for lifetime."

“The collection is beautifully crafted. The designs are airy and artistic and so easy to wear," she added.

The pieces begin at $79.99 and range right up to $999, and you can watch her interview with Ellen DeGeneres, in which she opens up about her weight gain, confidence and expectations of beauty, here:
