Blake Shelton and Miranda Lambert's marriage is on the rocks, according to a new report from the National Enquirer.

According to the publication, Shelton is allegedly "openly lusting" after his Voice co-star Christina Aguilera, and it’s sparked a huge blowout for the couple.

"Horndog Shelton," as the Enquirer coins the country singer, recently "confessed to having a crush on Christina, and Miranda is furious that he won't stop talking about her."

The source added: "She was really upset, especially after Blake gushed about how sexy Christina looked and how he wished Miranda had as good a figure. Miranda fears the temptation of being around Christina for long hours day after day may be too much for Blake."

Despite the reports, Shelton and Lambert are NOT having trust issues about their marriage.

Gossip Cop checked in with a source close to the country duo, who tells us the mag's story is "ridiculous."

Earlier this week, Aguilera opened up about her Voice co-judges, admitting the guys -- Adam Levine, Cee Lo Green and Shelton -- are like her family.

"I know these guys so well. They really are like my brothers, no joke," she told the November issue of Redbook. "There's a 12 year-old-boy in me who loves to come out and play with them."

The 32-year-old singer took time out from The Voice during the fourth season. She made the decision so she could spend more time with her five-year-old son Max.

"I needed to decompress, wind down the clock and just breathe. I needed to find out who I am outside of that red chair," she explained. "We did three seasons, and I wanted to disengage and have my life back and be with my son - put my sweatpants on and wipe my make-up off."
