Here comes the bridesmaid!
The possibly pregnant singer and Faison's Scrubs costar served as bridesmaid and groomsman for the intimate nuptials, which were held under a tent filled with white twinkling lights.
Simpson, who has yet to confirm or deny the baby-bumpin' rumors, did her best to hide her stomach yet again, wearing a black dress as she walked arm-in-arm with Braff.
"I was the maid of honor last night for my BF @caceecobb. She was the most beautiful bride I have ever seen in my life!," Simpson tweeted Saturday morning, along with a photo of herself strategically hiding her tummy with a bouquet of flowers as she stood beside her fiancé, Eric Johnson.
