Demi Moore is apparently set to take Ashton Kutcher's surname, to celebrate their fourth year of marriage.

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

Ashton also recently revealed how he and his wife make their marriage work: "The real trick is putting yourself around people you admire," he told Parade magazine. "That's why I married my wife. I locked in the brightest light in the room. My wife and I have an agreement in our marriage, and part of that contract is that we are going to shine our lights on each other."

"My relationship with Demi is so solid, thank God, and we're so communicative about the way that we're feeling that we don't allow space to come between us. I definitely believe that if you stop working at relationships, they go away."
