is taking legal action against In Touch Weekly
, fighting back against a recent report suggesting that the "Sangria" singer had checked into rehab following his split from Miranda Lambert.
Shelton is seeking at least $2 million in damages.
The mag's Sept. 28 issue featured a cover headline reading: The Real Story: REHAB For Blake. ET can confirm that Shelton, 39, has now filed a lawsuit for defamation and false light invasion of privacy against In Touch's parent company, Bauer Media, declaring that he is not currently in rehab -- nor does he have any plans to enter rehab.
According to the legal document filed in Los Angeles, California, and obtained by ET, Shelton specifically takes issue with allegations that he was unfaithful to Lambert during their marriage, as well as claims that members of his "close circle" had been attempting an intervention.
The suit also references and refutes an Aug. 10 issue of In Touch, in which the publication detailed an alleged "fling" that could have ended Shelton's marriage.
"Mr. Shelton, who is not a litigious person, was prepared to let the first cover go," the suit reads. "In Touch had assured Mr. Shelton that it was going to leave him alone. Apparently, that was not the case. Accordingly, Mr. Shelton hereby commences this action both to set the record straight ... and to recover damages for the harm Bauer has done to his reputation."
On Oct. 7, Shelton tweeted vaguely
about the many headlines and reports circulating about him, writing: "The stuff I read about myself blows my mind. Shouldn't I get to do all these things since I'm already accused of them? #doublejeopardy."
