Rob Kardashian has kept a low profile for the past several months, but cameras spotted him driving around Los Angeles on Wednesday.

Photographers at X17 snapped the youngest Kardashian child behind the wheel in his Calabasas neighborhood wearing a black T-shirt and sporting a mustache.

The 28-year-old son of Kris Jenner and Robert Kardashian has stayed out of sight from the cameras, and his family has tried to stage interventions to help him through his "emotional issues," according to People.

"He's sad, he's bitter, he's single. He is very depressed and has been [for a while]," a source told People in March. "It's really hard for him that his sisters are so public and he looks like the shut-in."

He has gained a substantial amount of weight in the past year and the subject came up on a recent episode of "Keeping Up with the Kardashians." Kris recently shot down rumors that Rob had check into a rehab facility for his drug and alcohol addiction.

Older sister Kim Kardashian mentioned her brother the other day after Caitlyn Jenner made her debut on the cover of Vanity Fair magazine. Kim revealed that Rob didn't recognize Caitlyn at first glance, but later gave her a call to tell her how beautiful she looked.
