Ellen DeGeneres and longtime girlfriend Portia de Rossi are jumping at the chance to get married.

DeGeneres announced their engagement during a Thursday taping of "The Ellen DeGeneres Show," telling the Los Angeles studio audience the news that the California Supreme Court had struck down state laws against gay marriage.

"So I would like to say now, for the first time, I am announcing: I am getting married," she said during the show, which aired Friday.

The studio audience leapt to its feet for a long ovation, and De Rossi ("Ally McBeal," "Nip/Tuck") was sitting in the audience, beaming and clapping.
