Katy Perry is the latest celebrity ambassador to join Dita Von Teese and N.E.R.D. in H&M’s “Fashion Against Aids” and “Designers Against AIDS” charity campaign.

The over-the-top singer has designed a collection of printed bodysuits — featuring a smiley face inside a heart and retailing for $14.90 — will be sold at H&M Divided Stores across the Globe this month in a bid to raise awareness about the HIV/AIDS epidemic.
