Demi Moore is marking the fourth anniversary of her wedding to husband Ashton Kutcher by taking his last name as her own.

Kutcher married the Ghost star in 2005, becoming stepfather to her three daughters from her previous marriage to Bruce Willis.

The actress has so far refused to alter her name - but now she has decided to officially become Demi Kutcher, according to reports.

A source tells Britain's The People, "Demi didn't want to change her name at first because it didn't seem right but now she finally feels ready."
