Demi Moore's boozing fueled split?

Ashton Kutcher’s philandering ways may not have been the sole cause of his recent split from wife of six years Demi Moore.

According to a new report in Life & Style magazine, Moore’s alleged failure to stay on the straight-and-narrow created a huge rift in the marriage. That said, it’s unclear which came first: Kutcher’s affairs or Moore’s fall off the wagon.

“Demi had been sober for a long time — decades — but recently it’s gotten bad,” an insider told Life & Style. “Ashton loves her, but he can’t stick around and watch her do this to herself.”

Unsurprisingly, Moore’s rep denied the report.

L&S’s source went on to say: “Her daughters — Scout, Rumer and Tallulah — and her ex-husband, Bruce Willis, want her to be healthy. The whole family is taking a stand to help Demi.”
