Pop star Prince's second wife Manuela Testolini Nelson has filed for divorce from the musician.
Prince's first marriage ended in 1998
Ms Nelson's lawyer Edward Winer said it was a difficult decision for her to seek the divorce, adding that she hoped for a "co-operative resolution".
Prince, 48, has rarely spoken publicly about his marriage to Ms Nelson.
His first marriage, to dancer Mayte Garcia, took place in 1996 but only lasted two years. His lawyer had no comment on the current proceedings.
