Stevie Wonder has filed for divorce from his wife of 11 years, reports Reuters. It's not a huge surprise, though, given that he and fashion designer Kai Millard Morris have been separated since 2009, notes the Daily News.

TMZ has a copy of the filing, in which Wonder uses his real name—Stevland Morris—and signs with two fingerprints. Click for that.
