The surprise ceremony was held at a home in Malibu, and was attended by family and close friends including Jennifer Lawrence, Jennifer Aniston, Jake Gyllenhaal, Larry David, Judd Apatow, Chelsea Handler and David Spade.
Amy wore a stunning romantic A-line Monique Lhuillier bridal gown with thin straps and floral embellishments. Her hair was pulled into a low ponytail, with loose waves framing her face. She shared the first series of photos with the caption: "Yup."
Comedian John Early officiated the wedding, and Amy and Chris wrote their own vows and they were "hilarious" according to reports. Amy's sister Kim and another friend were the "best women" and wore pink tulle gowns with floral embroidery and a satin bow.
Photos added to Amy's Instagram story show that SNL stars Aidy Bryant and Vanessa Bayer either sang or gave a toast at the wedding, and that Amy's first dance with her father was to Hearts And Thoughts by Pearl Jam.
