Simpson, who is expecting her second child with fiance Eric Johnson, served as one of Cobb's bridesmaids in a long black dress and carried a bouquet of red roses. The pregnant singer walked down the aisle with the help of groomsman Braff, 37. Simpson's separated parents, Tina and Joe, fiance Johnson, and her younger sister, Ashlee Simpson, also attended the ceremony.

On Sunday, Simpson tweeted, "I was the maid of honor last night for my BF Cacee Cobb. She was the most beautiful bride I have ever seen in my life!" She also shared a photo of herself hiding her bump behind her bouquet while posing with Johnson.
