Stevie Wonder, the 62-year-old musical superstar known for hits such as "I Just Called to Say I Love You" and "Superstition," has filed for divorce, Entertainment Weekly reported.

Wonder married Kai Millard Morris, who works as a fashion designer, back in 2001. The spilt has been confirmed by one of Wonder's representatives.

As TMZ pointed out, this divorce is far from sudden -- the two have been separated since October 2009. Wonder and Morris have two sons together: Kailand and Mandla, 10 and 7, respectively.

According to the court papers that have been filed, Wonder will be seeking joint custody of the children, TMZ reported.
