LOS ANGELES (AP) -- Court records show Melissa Etheridge has filed to make her breakup with former girlfriend Tammy Lynn Michaels official.
The singer filed to dissolve her domestic partnership with Michaels on Friday in Los Angeles. They announced their separation in April, and the rocker told Oprah Winfrey it was mutual, but "sad."

The two held a commitment ceremony in 2003 and registered a domestic partnership in August 2005. Michaels gave birth to twins from an anonymous sperm donor in 2006.
The 49-year-old Etheridge cited irreconcilable differences for the split in court filings. She is asking to share joint custody of their 3-year-old children.
