The 62 year-old, who married fashion designer Kai Millard Morris in September 2001, cited irreconcilable differences. The couple have been living separately since 2009. Wonder, whose real name is Stevland Morris, was born blind and signed the divorce papers using two fingerprints. He has requested joint custody of their two sons, 10-year-old Kailand and Mandla, seven.
Wonder has five children from earlier relationships.
The pair first met in 1999 at Nell’s, a New York nightclub. She was working as a freelance art director and had been obliged to attend a party for work purposes, and when told that “a friend” wanted to meet her she almost refused.
“I said, ‘I’m sorry. I’m here on business’. I turned around and literally ran into Steve,” she said. “Then the man said: ‘This is who I wanted you to meet.'” The couple were left alone to talk until 5am, and six months later they were engaged.
Together they led a glamorous lifestyle, flitting between their Los Angeles home and New York, singing and designing for the world’s most high-profile celebrities.
Mrs Morris launched her own fashion label, Kai Milla Designs, whose fans included such luminaries as Michelle Obama and Eva Mendes, until it closed two years ago. Meanwhile Wonder, a child prodigy who has 22 Grammy Awards, sang Signed, Sealed, Delivered at President Barack Obama’s inauguration.
But the marriage, Wonder’s second. was not to last. The singer has employed celebrity lawyer Laura Wasser, who has previously represented Britney Spears, Kim Kardashian and Maria Shriver. In his divorce papers, he agreed to pay financial support for his estranged wife and their children. But he also requested that all his earnings since the separation be kept separate from the couple’s joint assets, a sign of a possible financial battle ahead.
