Comedienne Ellen DeGeneres tied the knot with long-time girlfriend Portia de Rossi in an intimate ceremony on Saturday, reports the online edition of People.

“Ellen DeGeneres and Portia de Rossi were married tonight in an intimate ceremony at their home in Los Angeles,” a spokesperson for the couple said.

DeGeneres, 50, a popular daytime talk show host made headlines in 1997 when she came out on her hit ABC sitcom Ellen.

De Rossi, 35, is an Australian-born actress who gained fame on the hit sitcom Ally McBeal and more recently appeared on Fox's sex-obsessed plastic surgery drama Nip/Tuck.

The couple have been dating four years and announced their engagement during a May taping of DeGenere's talk show, The Ellen DeGeneres Show. The union may be the highest-profile gay marriage since California legalized gay marriage in June.

Guests at the wedding included both women's mothers.

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.'”
