This one comes from the National Enquirer, so take it with a grain of salt, but Miranda Lambert allegedly threatened to punch out another shop owner near her Pink Pistol boutique in Oklahoma.
The Enquirer says that Melanie Peden opened her antique store a few doors down and invited Miranda over to check it out. And that's when Miranda supposedly went on a tear. Peden says, "She just walked around the place scowling at everything and finally blurted out that I stole this property from her... She had a complete meltdown and threatened to ‘punch me in the mouth’ if I kept talking... I was stunned and a little bit scared too, because she was growling and yelling at me like a crazy lady."
Peden has apparently filed a police complaint.
