Reason for Concern?

Rob Kardashian was snapped at Los Angeles International Airport Sunday en-route to Europe for his sister Kim Kardashian's wedding to Kanye West, where the 27-year-old Kardashian appeared to be heavier than ever.

Rob, who has admitted to struggling with his weight in the past, has not been photographed in weeks prior to the LAX sighting. Accompanied by his mother Kris Jenner, Rob looked almost unrecognizable in a pair of loose pants and a black t-shirt.

According to Us Weekly, Rob had been doing daily workouts with sister Khloe Kardashian's trainer Gunnar Peterson for months, but he may have a "thyroid" problem. He also "binge eats" the magazine reports.

On an episode of Keeping Up with the Kardashians, Rob admitted he gained 40 pounds after his break-up with singer Rita Ora.
