Justin Bieber is known for helping charities, and last year the singer started a campaign,  “Schools 4 All” (School for All) , which raises funds to build schools in developing countries. The campaign is developed by Pencils of Promise , an organization that supports Bieber since the beginning of his career.

In the campaign, there is a collection system where students help other students disadvantaged by donating $ 25 (about £ 48) while competing with your school for the chance to make a private visit Justin in it. The school that receives the most fundraising visit by Canadian superstar.

A few days ago, we had the visit of the campaign and the winners were four students in the 9th grade, the Epiphany Catholic School, Illinois, USA. The group led the campaign raising $ 21,000 (about £ 41,000) .

The girls found that winners have won the visit through a Skype conversation with the office of charity in New York, on Monday (11).

“They were so adorable, jumping, crying, crying and thanking us,” said a spokesman for the organization, Rachele Aidala.

“The whole school heard us very well,”  said the student of Epiphany School, Sarah Thakral, one of which was raising funds.

“The date of the visit of Canadian singer, songwriter and actor has not been determined,” said Aidala. “It’s a visit to the school, not a show. But last year he sang some songs.”
