Lisa Marie Presley Files for Divorce from Michael Lockwood

Lisa Marie Presley has filed for divorce from husband Michael Lockwood, her rep confirms. In court documents obtained by PEOPLE, she cites irreconcilable differences in papers filed on June 13.

The pair were married in 2006 and have twin 7-year-old daughters, Harper Vivienne Ann and Finley Aaron Love. Presley has requested full custody of the children, offering Lockwood monitored visitation. She is reportedly not asking for spousal support or child support. "She doesn't want any of his money," a source told TMZ, who was first to report the news.

This was the fourth marriage for the 48-year-old daughter of rock icon Elvis Presley. In addition to high profile unions with Michael Jackson and Nicolas Cage, she was also married to Danny Keough – with whom she had two children, son Ben and daughter Riley Keough, an actress.
