DONALD FAISON from "Scrubs" married JESSICA SIMPSON'S best friend CACEE COBB over the weekend . . . and Jessica was a Bridesmaid.

--She walked the aisle with "Scrubs" star ZACH BRAFF.  The wedding actually took place outside Zach's Los Angeles home on Saturday.

--And of course, all the attention in the media is on Jessica's form-fitting bridesmaid's dress, and whether or not she looked pregnant in it.  (--Here are some pictures.)  (Popsugar)
