The famous family have rallied around as it's reported the athlete has a 50/50 chance of survival
Rob Kardashian has broken his silence as his "brother" Lamar Odom continues to fight for his life after being found unconscious in a Nevada brothel.
In a rare Instagram post, Rob shared a touching picture of him hugging former NBA star Lamar.
He wrote: "Praying nonstop for my Brother!!"
Mum Kris, who was pictured looking sombre outside the hospital where Lamar remains in critical condition, also took to social media on Wednesday afternoon to publicly show her support for her former son-in-law.
Kris and Rob's posts come after Kendall, 19, shared her own heartbreaking tweet.
The model, who has also now flown to Vegas to be with Lamar, begged "please don't go," in a simple but poignant message on her account.
Meanwhile, workers at the Nevada brothel where Lamar was found unconscious said the former NBA star - who is said to have a 50/50 chance at survival - had been using cocaine in the days before the incident.
The 911 caller, Love Ranch media director Richard Hunter, claimed the 35-year-old, who remains in a "critical condition" in the Intensive Care Unit of the Sunrise Hospital in Las Vegas, had cocaine with him on Saturday when he arrived.
He also told operators that the 35-year-old had used up to 10 tabs of sexual performance enhancers - herbal Viagra - during his stay.
During Wednesday afternoon's press conference, the Nye Country Sheriff's Office also said there's a possibility Lamar could be charged with drug posession.
The former Lakers player is reportedly likely to have suffered "brain damage" as a result of a "loss of oxygen but also possible stroke," and doctors are treating the situation as a non-suicidal "overdose".
