Miranda Lambert and Blake Shelton may be headed for divorce, In Touch Weekly reports, via Radar Online. The country music couple apparently is spending less time together, and rumors swirled that Shelton is cheating on his wife of three years.

“They’re barely together,” a source told the magazine. “Miranda is worried that if this keeps up, they’ll continue to grow apart.”

One factor that has split the two is that Lambert does not drink with “The Voice” mentor anymore after she lost 45 pounds, and he’s a notorious drinker. “She wants Blake to stop partying so hard and get healthy like she did,” the source said. “But he has no plans to slow down.”

Shelton also has a reputation for a wandering eye and apparently likes to flirt with other women. This has created “trust issues” with Lambert even though although he vehemently denies cheating.

Moreover, Lambert, 30, apparently can’t stand Hollywood life, while Shelton, 38, enjoys being on “The Voice” and his role as a reality TV judge. She reportedly stays at their Oklahoma home while he does the show.

The Inquisitr insinuated the couple could be heading towards divorce since Shelton said on “The Ellen DeGeneres” show Sept. 15 he did not want to have children. When the funny lady asked “The Voice” judge about reproducing he said, “Ah … I mean … no!” DeGeneres seemed taken aback by his answer, but apparently one person in particular was really surprised: his wife.

“Miranda was absolutely floored! She believed the only thing to save their marriage was a baby – and now it’s not happening,” a source told the National Enquirer. "On top of that, her good pal Carrie Underwood is now pregnant, and that’s only rubbed salt in the wound.”

Shelton admitted he and his wife have “had our ups and downs for damn sure,” Radar Online wrote. Still, Lambert is reportedly desperate to avoid a divorce.
