But one family member who opted not to partake in the night's festivities was Kim's younger brother, Rob Kardashian.
"Rob did come to Paris but skipped [the rehearsal dinner at] Versailles and the wedding," says the source. "He just didn't want to see a bunch of people both nights and really just is not feeling like himself."
The sock designer arrived in Los Angeles Saturday night just as his sister walked down the aisle.
While Kardashian was spotted working out with trainer Gunnar Peterson at his hotel while in Paris, the former Dancing with the Stars contestant has been struggling with his weight for some time.
"He is really overweight and having a hard time with it," explains the source. Some reports cite a big family fight as the catalyst for the 27-year-old skipping the nuptials but says the source, "There was no big fight between him and Kim. This was just a decision he made."
