Ellen and Portia Are Newlyweds

In an intimate ceremony Saturday evening, Ellen DeGeneres and Portia de Rossi, exchanged personal, handwritten wedding vows witnessed by 19 of their closest family and friends at their home in L.A.

"What can I say? I'm the luckiest girl in the world," says DeGeneres. "She's officially off the market. No one else gets her. And now she'll cook and clean for me."

The couple both wore Zac Posen and exchanged rings by Neil Lane while they sat on floor pillows along with author Wayne Dyer, who officiated the ceremony.

"The love we felt from the people surrounding us, and the love we have for each other, made this the most beautiful and emotional day," says de Rossi. "And one that we'll never forget."

The celebration featured floral arrangements by L.A. florist Mark's Garden; David Silberkleit, the couple’s personal chef, prepared an all-vegan menu, and Sweet Lady Jane bakery created a vegan red velvet cake for the occasion.

DeGeneres, 50, and de Rossi, 35, provided an exclusive interview and photos to PEOPLE magazine.
