On today's episode of The Ellen DeGeneres Show, Ellen will announce that she and long-time girlfriend Portia de Rossi are getting married.

Her announcement is in response to this week's ruling from the California Supreme Court that everybody has a "right to marry" whomever they choose. The justices ruled that the state's ban on gay marriage is unconstitutional. It makes California the second state, after Massachusetts, that will allow same-sex marriage. The legal battle began in San Francisco when the mayor allowed same-sex couples to marry (Rosie O'Donnell and her partner, Kelly, married at that time).
