Akon was to perform in Sri Lanka next month and a major tourism drive was also launched to attract fans from Asia and other regions for the concert.
The decision came after some Buddhist monks asked the government to cancel the concert, accusing the Senegalese-American lyric, singer and producer of degrading Buddhism in his video "Sexy Chick". The video shows Akon dancing with a group of women around a Buddha statue at a pool party.
The visa was rejected after a deliberate discussion over the issue between President Mahinda Rajapaksa and Tourism Minister Achala Jagoda Tuesday, tourism ministry sources told Daily Mirror online.
However, Lasantha Samarasinghe, Director of Platinum Entertainment, the organiser of the Akon's concert, said that he has no information about the government decision.
"We will take this up with the relevant authorities tomorrow," Samarasinghe was quoted as saying.
