The latest high-profile Hollywood donation supporting gay marriage in California comes from director Steven Spielberg and his wife, actress Kate Capshaw, who donated $100,000, reports Variety.

The couple donated the money to the Equality for All/No on 8 campaign, the main group working to defeat Proposition 8.

Gay marriage is currently legal in California after a May Supreme Court ruling reversed a 2000 voter-approved gay marriage ban. Since then thousands of gay and lesbian couples have married.

Passage of Proposition 8 would constitutionally forbid gay marriage in the State and invalidate the thousands of gay marriages which have already taken place.

“By writing discrimination into our state constitution, Proposition 8 seeks to eliminate the right of each and every citizen in our state to marry regardless of sexual orientation,” the couple said in a statement. “Such discrimination has NO place in California's constitution, or any other.”

The gift equals that of Hollywood actor Brad Pitt, who announced he would donate $100,000 in support of gay marriage to the No on 8 campaign last week.

Openly lesbian actress Cynthia Nixon praised Pitt for his support of gay marriage. “I think the way Brad Pitt and Angelina Jolie always give their money, and the things they give it to, and the enormous amounts they give of it is just incredibly commendable,” Nixon told the Online edition of People.

“I think they inspire other people to give as well,” Nixon said before the Spielberg-Capshaw donation was announced.
