Showing her support for gal pal/blushing bride CaCee Cobb, Jessica Simpson served as the Maid of Honor at the Cobb/Faison wedding on Saturday afternoon (December 15).

The “With You” songstress donned a gorgeous black dress and walked the aisle with Best Man Zach Braff as CaCee said “I Do” with “Scubs” stud Donald Faison at a private Los Angeles residence.

And it sounds like Jessica had a wonderful time at the festivities, as she tweeted a picture of herself hiding her baby bump beneath a bouquet of flowers.

Along with the image, Simpson added the caption, "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!"
