John Mayer is urging his fans to donate money to provide anti-malaria nets for families in third world countries - so poverty-hit kids can live to the same age as teen sensation Justin Bieber.
The rocker has filmed a new public service announcement (PSA) for the MalariaNoMore charity, which aims to stamp out the killer disease by providing protective sheets to ward off mosquitoes.
And in a bid to take the campaign to a younger audience, Mayer is urging viewers to help affected youngsters live to the same age as 16 year old Bieber - insisting if the scheme works, future age targets will include those of the Jonas Brothers and Twilight star Robert Pattinson.
In the film, Mayer says, "Almost a million people a year die of malaria, and out of that number 85 per cent die under the age of Justin Bieber. With your help, by buying a mosquito net for just $10 we can help - by the end of the year - to get to Bieber. Next year, we'll go Jonas Brothers. After that, Twilight kids. But baby steps."
