Congrats to Ellen DeGeneres and Portia de Rossi: the couple wed on Saturday night at their Beverly Hills home.

De Rossi, 35, wore a backless, light pink dress, and her hair in a loose updo. DeGeneres, 50, dressed in pants, button-up shirt and vest–all in white.

Before the intimate ceremony attended by about 20 guests, “Ellen and Portia came out and posed for pictures with Ellen’s mom and their two dogs,” a witness tells Usmagazine.com.

“They were hugging and kissing, and looked ecstatic,” the onlooker adds. “Ellen was helping Portia with the train of her dress, which looked like a Cinderella tutu.”

The pair, who “were both laughing,” walked “all over the lawn together holding hands and posing,” the witness tells Us. “The whole afternoon seemed light-hearted.”

Earlier, workers were spotted bringing in bunches of pale pink and red roses.

Ellen and Portia got engaged in May, shortly after the California Supreme Court legalized same-sex marriage.
