The rumor mill is straining when it comes to Demi Moore & Ashton Kutcher. Although the much-talked about couple are in the midst of fighting off infidelity banter from critics and fans alike, they seem to be showing a united front, at least in public.  Full of giggles, jokes and all sorts of PDA, Moore and Kutcher were all smiles on the set of Moore’s new film The Reasonable Bunch last week, according to People. “Demi and Ashton got here in the early hours of the morning, and you could hear them laughing and carrying on from inside her trailer,” says a source.  The pair, whose fifth anniversary is quickly approaching, are faced with claims that Kutcher cheated with a 21-year-old.  But if the two are troubled at all by these serious accusations, they certainly aren’t letting on.

How can you stop cheating rumors from circulating?

Cupid’s Advice:

There’s no doubt about it — rumors, especially negative ones, are tough to deal with and difficult to hear.  And the age-old advice, “don’t dignify a rumor with a response” doesn’t always work.  Cupid has some suggestions for ways to halt rumors before they spiral out of control:

1. Prove the rumor isn’t credible:  The people who start rumors want other people to believe they’re telling the truth.  So, they make sure that what they’re saying is plausible.  To stop the news before it spreads, determine what makes the rumor credible in the first place.

2. Keep it simple: One of the worst things you can do in the face of a dirty rumor is to appear defensive and angry.  There’s no reason to let it get that far.  If you have evidence to the contrary, just say, “That can’t be true, because …” and leave it at that.

3. Create a new truth: The reason gossip exists is because it’s fun to know things about other people that they’re probably trying to keep to themselves.  If you find yourself the subject of rumors, introduce a new rumor — one you can control more easily.  People will stop focusing on the old news and put their attention to the new information they just got.
