Ananova:

A Chilean rock star is asking female fans to send him pictures of their naked bums.

Julio Carrasco, frontman of Los Muebles, launched the campaign which he calls 'an a**hole for Los Muebles'.

He made the appeal through the Chilean media for fans to post their pictures to website malasya.blogspot.com.

Carrasco told Las Ultimas Noticias he hopes to get 1,000 pictures of the bottoms of female fans.

He will then pick out the top five to give them a surprise award.
