Rob Kardashian -- brother of the bride-to-be -- was spotted at LAX Sunday as he and the rest of the Kardashian/Jenner clan began to make their way to France for Kim's big wedding.
Despite reports ... we're told Rob has not been at "fat camp" or any other form of rehab ... rather he's been working out frequently with a big name trainer to battle his weight problem.
Either way ... he's going to have to alter his tuxedo a bit from Kim's last wedding.
