Jessica Simpson is wearing her wedding ring again - but insists she isn't back with estranged husband, Nick Lachey. The Newlyweds stars split last year after three years of marriage, and the pair are in the middle of divorce proceedings.

Jessica has now been spotted wearing the wedding band on a chain round her neck rather than on her finger. A friend of the singer-turned-actress insists the blonde has decided to wear it again to remind herself of the happy times the couple shared.

The pal told People magazine: "You can still move on and have the memories. Nick will always be an important part of her life."

The ring is accompanied by two crosses, one that was given to Jessica by her parents, while the other matches a crucifix that both her sister, Ashlee, and mother, Tina, wear.

A source close the Dukes Of Hazzard star also revealed the jewellery represents "a combination of things that are important to her."
