LOS ANGELES -- Comedienne Ellen DeGeneres has tied the knot with girlfriend Portia de Rossi at a private ceremony in California, three months after the state ended a ban on same-sex marriage, a report said Sunday.

A spokesperson for the couple told People magazine they were married at their home in Los Angeles on Saturday.

"Ellen DeGeneres and Portia de Rossi were married tonight in an intimate ceremony at their home in Los Angeles," the spokesperson said.

DeGeneres, 50, and de Rossi, 35, were married before 19 guests including both women's mothers.

DeGeneres, a popular daytime television host who also presented last year's Oscars ceremony after a successful comedy career, had announced plans to marry de Rossi in May after California's Supreme Court ruled that a ban on gay marriage was unlawful.

De Rossi, 35, an Australian actress who rose to fame in the hit sitcom "Ally McBeal", showed off a three carat diamond ring given to her by DeGeneres at an awards show in June.

"She's taught me lessons about myself, and I feel like I've taught her," DeGeneres said of de Rossi last year. "We've both changed and grown, and we just feel like, 'Oh, okay, this is completion.'"

A spokeswoman for the couple had declined to comment on speculation the couple were poised to marry when contacted by AFP on Friday.

DeGeneres made headlines around the world in 1997 when she came out on national television in a two-part interview with Diane Sawyer before doing the same again on her hit television sitcom "Ellen."
