Madonna has angered her neighbors by hogging prime parking space outside her $40 million Upper East Side townhouse - arranging to install fake 'No parking' signs to scare other motorists away.

The fake signage includes a 'No parking' sign posted on the singer's security gate, and a 'Tenant parking only' sign mounted on a pole in a tree bed on the sidewalk. Both signs threaten that 'unauthorized vehicles will be towed away.'

The signs differ in design and language from official Department of Transportation notices.

The pop icon's people also had the words 'No parking' imprinted along the edge of the sidewalk, and painted the curb yellow.

The yellow paint job, curb imprint and the sign posted in the tree bed are all against city rules and subject to monetary fines, New York City DOT officials told Daily Mail Online.

Madonna has been issued a letter of defacement and has 30 days to respond if she wants to avoid a $250 fine, DOT officials said.

'We've all been wondering for a while now if these signs are real and everyone on her street has just accepted them,' a neighbor told Daily Mail Online outside the four-story Georgian-style townhouse Thursday morning.

MADONNA'S LIFE IN NEW YORK The pop star, whose full name is Madonna Louise Ciccone, first moved to New York from Michigan when she was 19. Her first apartment in the city was a four-story walk-up at 232 East 4th Street in the East Village, according to the New York Post. The Upper East Side townhouse was purchased for $40 million in 2009, according to the Post, which quoted a broker as saying that no other residence in the area 'has ever sold for $20 million, let alone $30 million — or ever will again.' The newspaper reported the property has 26 rooms, including 13 bedrooms, and 14 bathrooms — as well as 'a 3,000-square- foot garden, nine fireplaces, an elevator and a wine cellar with a grotto.'

'At first we thought it made sense as often you see middle age fans trying to catch a glimpse of her, so it looked like she had a permit to have them so she could come and go without being annoyed. We're now troubled that they could be fake as this just seems so entitled.'

But the signs aren't the only way Madonna, 57, annoys her neighbors.

'What has angered us the very most is that when she leaves one of her staff literally walks into the street and stops cars and pedestrians from passing.'

'This way she can leave from inside the garage and not have to deal with the public,' a neighbor said.

'It's really quite obnoxious and we all joke that she is playing "Bitch I'm Madonna" as her chauffeured car drives her by all of us minions waiting on the street for her to pass.'

The pop icon also had the words 'No parking' imprinted along the edge of the sidewalk, and painted the curb yellow.

'The funny thing about this is that the Upper East Side is divided into two sections West of Lexington and East of Lexington. Madonna lives East of Lexington. West of Lexington is where the super-rich live and she would never get away with this if she lived there.'

'West of Lexington they'd all either bitterly complain or her neighbors would want the same thing too,' the neighbor remarked.

With the conclusion of Madonna's most recent tour, Rebel Heart, which wrapped up in Sydney on Sunday, the pop singer officially became the highest-grossing touring solo artist on record, according to statistics from Billboard released Wednesday.
