Demi Moore has officially become Mrs. Ashton Kutcher after changing her name on her driving license and credit cards.

The actress wed Kutcher in 2005 but took her time in changing her name to his.

An insider tells America's In Touch magazine, "Demi did this for Ashton. She knew that this was something he wanted, so she finally made the switch."

The source says Demi will be Mrs. Kutcher on her black American Express card, her passport and other official documents, but the actress will keep her name from her first marriage to Freddie Moore for all her professional endeavours.
