Lady Gaga may be interested to hear that she's got a big fan in Minnesota, who roams the mall and sings to people. He claims to be buddies with her -- and Madonna, too.

An officer on 'Mall Cops: Mall of America' (Thu., 10PM ET on TLC) pulls the man aside for questioning. "You're turning back, behind people and singing to people," he tells the man, who has no ID and says he's from Los Angeles. "I don't think they want you singing to 'em."

So what's he doing in Minnesota? His friends Lada Gaga and Madonna are at the airport; he called them just "10 minutes ago." He tells the officer they're going to come shop together.

But, alas, they never show. Instead the guy begins to threaten the officers, throwing in some random designer brand names ("GucciArmani!") for emphasis. Don't worry, ladies, the paramedics are on their way.
