LOS ANGELES (AP) - Ellen DeGeneres has made a public service announcement urging California voters to oppose a ballot initiative that would ban same-sex marriage.

DeGeneres married actress Portia de Rossi on Aug. 16, two months after the California Supreme Court ruling that legalized gay marriage took effect. In recent days, the popular talk show host has been criticized in the gay press for not giving money to the campaign to defeat Proposition 8 or otherwise lending her star presence to the cause.

She still hasn't made a campaign contribution, but on Tuesday she posted a video on her show's Web site. She said when she got married it was the happiest day of her life.

DeGeneres' mother, Betty, has given $700 to help defeat the initiative.
