R&B star and king of auto-tune T-Pain canceled his performance in Guyana after receiving "credible death and kidnapping threats." The performance was scheduled for Monday's annual Carnival celebration before being nixed.

According to the promoter Kerwin Bollers, the threats were received via e-mails and phone calls from an unidentified source. As of Sunday, police commander Leroy Ballers said the threats were being investigated.

Guyana's yearly celebration called Mashramani is a celebration of harvest and features live performances and elaborate costumes. T-Pain was said to be one of the biggest names to hit the stage in the country.
