Blake Shelton and Gwen Stefani have been married for 10 months, but it's clear that their honeymoon period is over.

According to a source who spoke to OK magazine, the two high-profile celebrities have begun butting heads incessantly, and their close friends are concerned that their marriage may face even more problems.

"They've always gone out of their way to please each other, especially Blake, because Gwen is happiest when she gets her way."

However, the country artist has apparently been more pushy since they married, something the platinum blonde singer is not pleased with.

The couple has begun to put the final touches on their new dream house in Oklahoma, where they married in July.

But the projects have now turned into a whole nightmare for the pair since they reportedly "fight over every little thing," which the source noted might include bathroom tiles and kitchen cabinet knobs.

According to the insider, the decorating squabbles were so severe that the "Hollaback Girl" hitmaker began grumbling and backstabbing about the "Minimum Wage" singer's "tacky taste."

The purported squabbles between Gwen Stefani and Blake Shelton go beyond home design.

According to the source, Blake is irritated when Gwen picks what they'll have for dinner without first consulting him.

After all, Gwen is a vegetarian, but Blake eats potatoes and meat.

Gwen is also always concerned about her husband, who managed to gain some quarantine weight and then lose part of it, just to yo-yo back up again, according to the source.

"Gwen often gets on his case for leaving his items about the home," the source stated. "They even squabble about toothpaste because Blake never squeezes from the bottom!"

While their close friends and family are concerned about their constant squabbling, their disagreementsmay jeopardize their marriage.

Blake Shelton and Gwen Stefani are believed to remind themselves that the first year of marriage is "usually the worst," but they are determined to work it all out.

"It's a little early to be constantly pushing each other's buttons," the insider says.

The report from the source should be regarded with a grain of salt, as there is no evidence or indication that the couple's marriage is in trouble.
