According to divorce papers obtained by ET, Presley cites irreconcilable differences as the reason for the split, noting they separated on June 13. She is also asking for legal and physical custody of their two children, with monitored visitation for her soon-to-be ex.
These are Lockwood's only children, while Presley also has a daughter and a son -- Riley and Benjamin Keough -- from her first marriage to Danny Keough, which ended in 1994. In addition to Lockwood and Keough, Presley was married to Michael Jackson from 1994 to 1996, and to Nicolas Cage from 2002 to 2004.
This isn't the first summer split in music this month. Last week, Iggy Azalea announced that she was breaking off her engagement to NBA pro Nick Young. "Unfortunately although I love Nick and have tried and tried to rebuild my trust in him, it's become apparent in the last few weeks I am unable to," the 25-year-old rapper posted to Instagram. "I genuinely wish Nick the best. It's never easy to part ways with the person you planned your entire future with, but futures can be rewritten and as of today mine is a blank page."
