Katy Perry has some pretty hardcore fans but she certainly knows how to treat them.

The popstar has given pillows and blankets to them, emblazoned with the words 'Teenage Dream', in order to make their stay more comfortable as they wait to see her perform today at a free outdoor concert in New York City.

The concert is part of Perry's promotion of her latest album, Teenage Dream' on 'The Today Show'.

Perry wrote on her Twitter, "I had special Teenage Dream pillows & blankys made just for those of you that are camping out for The Today Show! Yay!"
