"[She] used our children as pawns," the rocker, 49, says in court papers released Thursday in her increasingly bitter split with Tammy, 35.
In other papers released Thursday, Tammy revealed her finances as she continues to seek support from Etheridge.
The former actress, who is a full-time homemaker and has no income, states that her rent is $6,000 a month and she spends $1,500 on groceries and household supplies, $50 on laundry and cleaning and $800 on dining out with her children. Before the split, her monthly clothing budget was $5,000.
The former Tammy Lynn Michaels suggests that Melissa can easily afford to support her and the twins, estimating that the rocker earns between $600,000 and $750,000 a month.
Tammy also asks for $4,300 a month for childcare, so that she can work or get job training.
Melissa's attorney told a judge on Monday that Melissa gives Tammy $2,000 a month and pays all of her household bills.
