Ellen DeGeneres surprised by Portia de Rossi in white dress for wedding vow renewal ceremony

Nearly 15 years after they said "I do," Portia de Rossi surprised wife Ellen DeGeneres with a vow renewal at home in front of their family and friends.

During a party Tuesday for de Rossi's 50th birthday, the actress left the former talk show host speechless after stepping out in the original ivory gown she wore for their wedding in 2008. Singer-songwriter Brandi Carlile performed "The First Time Ever I Saw Your Face" as de Rossi led a visibly stunned DeGenres to the front of the room.

"Oh my God," DeGeneres, 65, said after turning to see Kardashian-Jenner family matriarch Kris Jenner standing ready to officiate the ceremony.

"Welcome to Portia's birthday party and to the newest home of one of my favorite couples, two of my BFs and the record holders for the most homes ever purchased in one city, ever. Literally," Jenner read off a sheet of paper. "These two are couple goals who continue to amaze me with how cute they are together. A match made in heaven. Two peas in a pod. Their love and commitment to one another is amazing and it makes me so happy that they have each other to love and cherish and grow old with."

DeGeneres and de Rossi originally married at their home in Beverly Hills on Aug. 16, 2008, in front of 15 guests, Jenner noted. She added: "Today, Portia would like us to witness a renewal of her commitment to Ellen, to honor and celebrate their marriage of 14 years."

"Surprise," de Rossi began, prompting laughter from their guests. "You don't have to say anything at all, but when I was thinking about what would make my birthday really special, apart from being with family and friends, it was reminding you that you're the most important thing in the world to me in front of family and friends. I was thinking about my life, my accomplishments, as you do with a big birthday, and it all just kept leading back to you, and I just thought, 'What greater accomplishment could I ever, ever, ever have in my life than being loved by someone who is so magnificent, by someone as incredible as you?'"
