Bridal bliss times three!

When Nicole Richie married Joel Madden on Saturday, the author and fashion designer wasn't content with just one bridal outfit. Instead, Richie, 29, donned three different looks, all by Marchesa, a source confirms exclusively to UsMagazine.com.

The insider explains that Richie wore one gown during the ceremony (which was officiated by rapper-minister Rev. Run); for the dinner, she kept the same top and switched into a different dress; for the after-dinner party, she changed into another Marchesa frock.

What did Richie, Madden, 31, and their 150 guests (including Khloe Kardashian and Samantha Ronson) chow down on at the fete, held at her dad Lionel's Beverly Hills estate?

TMZ unearthed the menu from the winter-themed affair: The gourmet goodies included red greens salad, homemade butternut squash ravioli in brown butter sage sauce, an entree choice of filet mignon or seared ahi tuna and a dessert buffet.

A guest tells Us the bash --  also featuring an elephant! -- was "awesome."
