Katy Perry, Cyndi Lauper, Yoko Ono and hip-hop group N.E.R.D. have joined forces to front clothing store H&M's new Fashion Against AIDS collection.
The artists have all come up with their own T-shirt designs for the charitable line, with 25 per cent of the profits going to non-profit organisations like Designers against AIDS, MTV's Staying Alive Foundation and YouthAIDS.
Dita Von Teese, Estelle, Robyn and Roisin Murphy are also among the celebrities getting involved. The shirts will hit the high street stores worldwide from 28 May (09).
