Rob Kardashian and his mother Kris Jenner were spotted at LAX Sunday as the duo headed to Europe for Kim Kadashian's upcoming wedding to Kanye West.

Kardashian, who has been struggling with his weight for over a year, had not been photographed in weeks before Sunday's outing.

According to x17, the sock designer reportedly enrolled in fat camp in April, but hasn't lost any weight yet.

In early April Kardashian shared a troubling post on Twitter writing that "no one will ever understand how much it hurts."

While the reality star deleted the message the following day, sources close to the situation claim he is "really depressed" as he continues to struggle to lose weight.

Kim Kardashian and West are expected to marry this coming weekend at an undisclosed location.
