Ellen DeGeneres says she is "saddened beyond belief" by the passage of a constitutional amendment in California banning gay marriage.
The talk show host said in a statement to The Associated Press that she, "like millions of Americans, felt like we had taken a giant step toward equality" by electing Barack Obama as president.
DeGeneres says that with the passage of California's Proposition 8, "we took a giant step away."
DeGeneres wed actress Portia de Rossi in August, following a May Supreme Court decision legalising same-sex marriage in California.
She contributed $100,000 to fight the amendment on Tuesday's ballot.
DeGeneres asserts she will "continue to speak out for equality for all of us."
