Charity Keep Britain Tidy says it costs £27m a year in England alone to get rid of the painted pictures and tags.

The charity added that stars like Christina use graffiti in their videos to look cool and edgy, but also succeed in making it look cool to kids.

The charity hopes government plans to hand out fines and stop teens buying spray paint will stop some graffiti.

But not everyone thinks graffiti is nasty to look at and a big problem.

The Urbis Museum in Manchester is holding an exhibition of what it calls "street art".

The creative director at Urbis, Scott Burnham, said: "It is not celebrating graffiti. We have 10 of the best street artists from around the world who have been through formal training as artists but are working directly on the street."

More than 100 MPs - including the Prime Minister - back the charity, saying "graffiti is not art, it's crime".
