The momager and Khloe Kardashian rushed to be by the 35-year-old's side after learning of the sad news
While most of the Kardashian-Jenner family have been on social media lockdown, matriarch Kris has broken her silence after Lamar Odom was found unconscious in a Nevada brothel.
Khloe, Kris and Kim all rushed to be by the former NBA star's hospital bedside after learning of the news.
And Kris, who was pictured looking sombre outside the hospital where Lamar remains in critical condition, took to social media on Wednesday afternoon to publicly show her support for her former son-in-law.
Next to a picture of a happy Lamar taken during an LA Lakers game, she wrote: "Please pray for Lamar #ourfighter."
Rob Kardashian also later shared a post, writing: "Praying nonstop for my brother!!"
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.
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".
