Sean Kingston will spend 3½ behind bars, a judge decided Friday, for his involvement in a $1-million fraud scheme. His mom is serving 5 years for the same crime.

Kingston, 35, and his mother, Janice Turner, were found guilty in May of defrauding luxury businesses of more than $1 million.

Last March, Kingston was convicted by a federal jury of conspiracy to commit wire fraud and four counts of wire fraud.
