Actress Tammy Lynn Michaels claims her split with rocker Melissa Etheridge has left her penniless, $4 to be exact.

Celebrity website is reporting that Michaels' lawyer, Steven Knowles, says Etheridge has not given Michaels or their children a dime since their split, announced in April.

Michaels' wrote on her blog that Etheridge's filing of paperwork to end their California domestic partnership was a shock that left her “blindsided.”

Both women claim “irreconcilable differences” in their separate filings, but Etheridge is asking for joint custody of the couple's twin 3-year-old children, son Miller and daughter Johnnie Rose. Michaels, who gave birth to the twins, says she wants full custody of the children with visitation rights for Etheridge.

Forty-nine-year old Etheridge shares joint custody of two children, Bailey Jean, 13, and Beckett, 11, from a previous relationship with Julie Cypher.

Michaels, 35, said on her blog that she gave up her acting career in 2001 to care for the children.

Lawyer Knowles told PEOPLE that Michaels filed for a dissolution of marriage (instead of a dissolution of domestic partnership) because the couple considered their relationship a marriage. He said the filing was symbolic and that his client would amend the complaint if the court asked.

Michaels is more likely to prevail in her claim for spousal support if the court views their relationship as a marriage.

Etheridge lawyer Neal Hersh told TMZ that his Grammy-winning client is paying “all of Tammy's expenses.”

The women exchanged vows in Malibu, California in 2003. They reportedly attempted to marry during the 2008 June-to-November window when gay marriage was legal in California.
