Are Melissa Etheridge and Tammy Lynn Michaels headed for a custody battle?
Almost a week after the singer filed legal documents to end their partnership, Michaels also went to court to file her own papers.
But while Etheridge, 49, requested joint custody of the couple’s 3-year-old twins, Michaels, 35, is seeking full legal and physical custody, with visitation for Etheridge, documents filed in L.A. County Superior Court show. Michaels gave birth to son Miller and daughter Johnnie in 2006. She is also asking the court to grant her spousal support.
