It seems the mush heralded May-December relationship is on the rocks.

Rumors of infidelity by Demi Moore’s husband, Ashton Kutcher, has apparently dented the marriage. The couple, who has been together for six years, apparently celebrated their anniversay apart last Sept. 24.

Ashton had been seen in san Diego with his former “That 70′s Show” co star Danny Masterson and had been at the Fluxx nightclub enjoying their VIP table. He was later at an event with Ryan Seacrest.

Demi had been in New York to attend an event, the launch of “Five” where she is one of the five featured directors along with Jennifer Aniston.

The husband did not seem to tweet anything about their marriage on that day, while the wife had a few cryptic words saying, “When we are offended at any man’s fault, turn to yourself & study your own failings. Then you will forget your anger.”

She was quoting a Greek saying.

Earlier this week, a woman apparently threatened to reveal her sex tryst with Ashton Kutcher. But none of their representatives have been talking.

Ashton, 33 and Demi, 48 started dating more than five years ago after the actress split with her first husband, Bruce Willis.

Over the last year, the two have been on a “spiritual journey” in Israel, amidst another rumor that Ashton was seeing women behind her wife’s back.

Ashton and Demi has been a model couple for those with huge age differences and it seemed like Demi’s children love their step dad a lot.
