Where have you been, Rob?!

The troubled reality star was spotted in Calabasas, Calif. on Wednesday, June 3, after months of staying out of the spotlight. Sporting some noticeable facial hair and wearing a simple black t-shirt, Rob was snapped driving through the affluent neighborhood.

The 28-year-old Arthur George socks creator has been keeping a low profile these days, despite his sisters' constant presence in the spotlight. In April, Kris Jenner claimed on Keeping Up With the Kardashians that her only son had gained 100 pounds in the last year alone, when she discussed his problems with a life coach.

"I feel like if I don't help him do something drastic, that he's gonna die," she said through tears.

In an interview with Today's Matt Lauer late last month, Kim Kardashian called her brother's struggles "a phase."

"I think he's just going through a phase where he's not comfortable in his own skin," she said. "He is working really hard to get back to where he really wants to be."

Last week, Kris strongly denied to ET reports that Rob had checked into a 60-day Palm Beach rehab center that deals with drug and alcohol addiction, calling the rehab rumors "completely fabricated." The momager also took to Instagram to show off group texts between her, Kourtney, Khloe, and Rob, that seem to prove all is well between the famous siblings. Rob's text even reads, "Love u all babies."

Curiously, Kris explains Kendall and Kylie's absence from the group texts (Kylie is on a plane, Kendall's texts are cut off at the top) but not Kim's. The 34-year-old reality superstar has made no secret about her rocky relationship with Rob in the past, and he allegedly called her "the b**ch from Gone Girl" in a March Instagram post.

One family member Rob is clearly supporting, however, is Caitlyn Jenner. Though he has yet to comment on her big Vanity Fair cover, after Jenner's revealing 20/20 interview, Rob tweeted, "You have always been a role model to me and now more than ever, I look up to you. LOVE YOU‼️‼️"

But could there be some potential drama brewing between him and Kendall Jenner? The 19-year-old supermodel was spotted hanging out with her stepbrother's ex, Rita Ora -- who he's previously slammed -- at Cannes last month. Watch below:
