Mick Fleetwood goes his own way, separates from wife of 17 years Drummer Mick Fleetwood performs during a Fleetwood Mac concert at Madison Square Garden in New York. Picture: Jason DeCrow Source: AP COURT records show Mick Fleetwood has filed for legal separation from his wife of more than 17 years in Los Angeles. Fleetwood and Lynn Frankel Fleetwood have been married since July 1995 and have twin 11-year-old daughters. He is seeking joint legal custody but wants his estranged wife to have physical custody of their children. The Fleetwood Mac drummer filed for separation on March 22, but the documents were not publicly available until this week. He does not list a date for the couple's separation but wants a judge to award him sole control of music royalties and other earnings from before their marriage. The 65-year-old Grammy Award winner cites irreconcilable differences for the separation, but no other details are included in the filing.
