The burlesque queen and the "I Kissed a Girl" warbler are but two of the celebrities who've teamed up with H&M and Designers Against AIDS to help spread awareness of HIV and AIDS to today's youth.

Von Teese and Perry collaborated with H&M on designs for garments, which will go on sale in H&M's youth-oriented Divided department on May 28. Twenty-five percent of the sales proceeds from the 100-percent organic-cotton clothes will go to youth HIV/AIDS awareness programs.

Other celebrities and artists participating in the effort include Tokio Hotel, N.E.R.D., Cyndi Lauper and Moby. Check out a video of Perry and the other participants discussing the importance of the project below:
