Jessica Simpson's jewellery collection

Jessica Simpson says her new jewellery collection reflects her personality.

The singer-and-actress - who is currently pregnant with her first child - has designed an accessories line for Zales stores and says she was involved in every part of the process.

She said: 'This collection has allowed me to create pieces that truly reflect who I am. The pieces can become a keepsake for life.'

The collection - which features earrings, rings and bracelets and more - includes a variety of butterfly-shaped designs based on the star's handwriting.

Earlier this month, Jessica and her sister Ashlee launched their girls' clothing line, which is a reflection of both their styles.

Describing the new range, which is released through the Jessica Simpson label, pregnant Jessica said: 'It's a combination of both of our styles. Ashlee is very rock 'n' roll, and I'm very American.'

Jessica also revealed she has signed a deal for a maternity line and will also design girls' footwear.

She also admitted she may branch out further if she discovers she is expecting a son.

She said: 'Boys' clothing is a possibility.'
