Ellen and Portia Tie The Knot

Mazel Tov to Ellen DeGeneres and Portia de Rossi!

The lovely lesbians made honest women of one another when they tied the knot at their Beverly Hills Mansion Saturday:

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. [Both by Zac Posen.]

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.”

No word on where the ladies will be taking their honeymoon, but we suggest the Greek Isles…
