Tim McGraw and Faith Hill continue to face rumors about their marriage.

On the cover of this week's The National Enquirer, the tabloid blasts the headline: "Faith Devestated by Tim McGraw Gay Scandal."

According to the report, a former friend and bandmate of McGraw plans on publishing a memoir detailing the singer's "homoerotic hijinks."  In the story, the source claims McGraw's "risque" behavior is "not an indictment on the singer’s sexuality" though. 

Neither of the county singer's reps have commented.

Just last week, the National Enquirer alleged that the singers were divorcing. The Enquirer claims it has "uncovered the sensational details of the conflict that's left the superstar couple's marriage and their $135 million empire hanging by a thread."

In the report -- which has been denied by their reps -- Hill reportedly demanded that McGraw put his Nashville ranch on the market after she became concerned over McGraw's "sexual chemistry" with Taylor Swift. The story also alleged that Tim has been hiding a secret son from Faith.

According to the tabloid's sensational cover story, McGraw has been "threatening to walk for good", but his spokesperson has dismissed speculation of a split, telling EnStars the claims were "totally false and ridiculous."

Hill's rep also slammed the story as untrue.
