Melissa Etheridge filed papers to legally end her partnership with Tammy Lynn Michaels.
She wants joint custody of their 3-year old twins.
Melissa filed the papers at L.A. County Superior Court citing irreconcilable differences and asked the court to not award financial support to Michaels.
Etheridge and Michaels registered as domestic partners in August 2005 and surprised everyone when they announced that they were splitting in April. Melissa was the one who was done with the relationship.
