Melissa Etheridge says if California won't allow gays to marry, she won't pay her state taxes.
Etheridge writes in a blog on The Daily Beast that if she's not allowed the right to marry under the state constitution, she takes that to mean that she's not a "full citizen," so she doesn't have to pay taxes.
She says there's a lot she can do with the extra "half a million dollars" she'll be saving.
Etheridge has released ten albums in her career. Three of them have gone multi-platinum.
Etheridge is famous as a gay rights activist, having come out publicly as a lesbian in January 1993 at the Triangle Ball, a gay/lesbian celebration of President Bill Clinton's first inauguration.
She is also a committed advocate for environmental issues and in 2006, she toured the US and Canada using biodiesel.
Etheridge had a long-term partnership with Julie Cypher, which made headlines.
Local, state and national politics
During this partnership, Cypher gave birth to two children, Bailey Jean, born February 1997, and Beckett, born November 1998, fathered by sperm donor David Crosby.
Melissa Etheridge is now with her partner Tammy Lynn Michaels.
Etheridge lives in the Santa Ynez Valley in Santa Barbara County.
