If the tabloids claim your marriage is in trouble and nobody notices, should you even bother to deny it? In the case of Courteney Cox, 42, and David Arquette, 35, the answer is a resounding yes.

The couple is denouncing recent, if little remarked upon, reports from Star and Life & Style that allege their almost eight-year-old union -- in Hollywood terms, that's the equivalent of a golden anniversary -- is on shaky ground.

Star, in its "Courteney & David: On the Rocks?" story, wonders whether the dissimilar duo, "busy with separate careers and a toddler [2-year-old Coco]," are drifting apart, citing Cox's supposedly "flirty relationship" with her "Dirt" co-star Josh Stewart and Arquette's purported "neediness."

"Courteney is leading her own life and David is leading his," asserts an insider.

Life & Style, meanwhile, plays up the Jennifer Aniston angle, claiming Cox is leaning on her BFF, whom she bucked up during her bustup with Brad Pitt, to keep her "mind off her problems with David and on the future."

But the Arquettes' rep adamantly denies they've hit a rough patch, fuming to Us Weekly, "There is not a shred of truth to the rumors about the state of their marriage. They are happily married and, like most married couples, they have some separate friendships and interests."

Back in January, David fessed up to Howard Stern that he and Cox go to therapy "once in a while," but chalked up their sessions to "just stress from work."

And he was quick to clarify, "But I'm happy, don't get me wrong, I love her."
