She is a music and fashion heavyweight, and has sung about girls running the world, but who knew Beyonce had the power to buckle one of Europe's wealthiest economies?

The American diva known as "Queen B" is being blamed for pushing up inflation in Sweden where she began her world tour last month.

Economist Michael Grahn of Danske Bank said her showstopping Stockholm gig "probably" added up to 0.3 percentage points to inflation by pushing up hotel and restaurant prices there.

The news was a blow to Sweden's government which has been struggling to get it below 10 percent. But as Beyonce herself might say, "You must not know 'bout me."
