Singer-songwriter Lisa Marie Presley, the daughter of Elvis Presley, is getting divorced for the fourth time.
Lisa, 48, separated from husband Michael Lockwood on June 13 and has requested full custody of their seven-year-old twin daughters, sources confirmed.
She has filed for divorce citing irreconcilable differences in papers at Los Angeles Superior Court.
Lisa and musician Michael, 55, married in January 2006.
She was previously married to the late pop star Michael Jackson, actor Nicolas Cage and musician Danny Keough, who is the father of her daughter Riley, 27, and son Benjamin, 23.
Michael Lockwood served as main guitarist on Lisa's 2012 Storm & Grace tour and has worked with singers Carly Simon, Jon Brion and Aimee Mann.
Lisa is the only child of the late rock star Elvis and Priscilla Presley.
