US pop star Beyonce has angered a high-brow art museum in Vienna by sending a look-a-like to her own special personal tour of the museum, while she went shopping, according to newspaper reports Wednesday.

Tabloid dailies Oesterreich and Heute said the R&B diva had been due to visit the Albertina, one of the Austrian capital's most famous museums which attracts around one million visitors each year.

Recent visitors include Hollywood stars such as Brad Pitt, Angelina Jolie and Nicolas Cage.

But Beyonce, who gave a concert in Vienna on Tuesday, decided to skive off and do some shopping instead, sending a look-a-like to the museum and be photographed with Albertina director, Klaus Albrecht Schroeder, according to the reports.

The museum was understandably put out and said it would protest to the star's management.

"What a cheek," Albertina spokeswoman Verena Dahlitz told the Austrian news agency APA.

"We were a little doubtful yesterday, but weren't really sure. It could have been her," Dahlitz said, adding that fans were apparently duped, too.

Beyonce's concert in Vienna met with very mixed reviews and was only half-full, according to Oesterreich.
