Miranda Lambert Allegedly Threatened To Punch A Store Owner (REPORT)

Miranda Lambert may sing about "Gunpowder & Lead," but the country star allegedly threatened to use her fists when it came to a dispute with one of her neighbors.

The National Enquirer reports that the 29-year-old singer threatened to punch antique shop owner Melanie Peden, who just opened up her store just two doors down from Lambert's boutique, the Pink Pistol, in the small town of Tishomingo, Okla.

Peden told the Enquirer that she had invited Lambert to check out her store a few days before its grand opening, and when the singer stopped by on March 5, she allegedly began yelling that Peden stole the property from her. Peden says she knew Lambert had inquired about the property four years ago, but never made a formal attempt to purchase it.

“She had a complete meltdown and threatened to ‘punch me in the mouth’ if I kept talking,” Peden told the magazine. “I was stunned and a little bit scared too, because she was growling and yelling at me like a crazy lady. She’s got a real anger problem and needs help. But I stood my ground and asked her to leave my store.”

Tishomingo police confirmed to the Huffington Post that Peden filed a police report the day after the alleged incident.

Lambert most recently made headlines when she and husband Blake Shelton joked about rumors that their marriage was in trouble. If Lambert is in the middle of an ongoing investigation, it doesn't seem to be worrying her, as both she and Shelton appeared to be in good spirits when they showed up at "The Voice" Season 4 premiere party in Hollywood on March 20.

Request for comment from Lambert's rep has not been returned at this time.
