Family and friends, including Kanye West and Stevie Wonder, were among the guests.
Wonder performed with Legend as a special treat. Actress and model Brooklyn Decker was a bridesmaid and Biz Markie helped DJ the celebration.
Teigen, 27, wore three Vera Wang dresses for the big occasion, including an ivory strapless open back, V-neck ballgown for the ceremony, and an ivory strapless mermaid gown with a pleated bodice for the reception. She finished off her stunning looks with a crimson strapless mermaid gown with a hand-draped bodice and inverted flange skirt with crystal embroidery for the after party.
A source told US Weekly that the couple made the decision to say “I do” before Legend left to tour in October.
