UPDATE: Don't bust out the balloons and hold a pity party for Rob Kardashian just yet — the star's rep denies reports that Rob is drying out in an Arizona rehab facility. A source close to the reality star tells E! Online that, rather than battling his demons in therapy, Rob's battling the bulge in the gym, working out with celebrity trainer Gunnar Peterson as recently as this morning. While he may not be in a treatment center, Rob has been keeping a low profile recently, choosing to sit out a recent family trip to Thailand, as well as deleting the content from his social media accounts. 

Original story:Rob Kardashian’s personal issues have reached a boiling point, and now the 27-year-old Keeping Up With the Kardashians star is confronting his demons head-on.

Star (via RadarOnline.com) reports that the reality star has entered into a treatment program at Arizona’s Meadows Trauma and Addiction Treatment Center, where he’s been holed up for nearly a month working through depression and substance abuse issues.

While many of Rob’s issues, including trauma following the loss of his relationships with girlfriends Adrienne Bailon and Rita Ora, brother-in-law Lamar Odom’s alleged drug addiction and extramarital dalliances, and Rob’s sudden weight gain, played out in front of KUWTK cameras, it seems as though there are deeper issues afoot in the reality star’s life.

According to Star’s report, Rob entered treatment in part to recover from his habit of self-medicating with prescription cough syrup, weed, and booze, all of which have contributed to his weight gain, which he has admitted is a major factor in his low self-esteem.

Rob may be battling some pretty serious demons, but it’s clear that his “ride or die” family members have still got his back. Earlier this year, big sister Khloe Kardashian, who is no stranger to her own struggles with sorrow, particularly following her tumultuous final year of marriage to her estranged hubby, took time to show love to her little brother on social media, making it clear that his famous family won’t give up on him.

Last month, on Rob’s birthday, Khloe posted a collage of photos to Instagram, showing the pair in better times, along with a sweet message.

I would be lost without you!! Thank you for being the best brother anyone could ask for,” wrote Khloe. “This year I want to give you the ability to see yourself through my eyes! I want you to own how incredible you are and shine the way you are meant to shine.”

Are you surprised that Rob’s been dealing with such serious depression?
