Although an official update has not been given on Khloé Kardashian's ex-husband and NBA star Lamar Odom’s condition, a tweet from his former sister-in-law, Kendall Jenner, hints that the situation is grim. Odom, 35, was rushed to the hospital Tuesday late afternoon after being found at the Love Ranch South brothel in Pahrump, Nevada.

Kendall’s tweet comes shortly after Odom’s longtime agent, Jeff Schwartz, released a statement to the media. Schwartz said that the Excel Sports Management family is “keeping him in our thoughts and prayers” but that they have “no additional information or comment at this time.”

According to reports, Odom was at Dennis Hof’s Love Ranch South since arriving Saturday. Odom was rushed by ambulance to a Las Vegas hospital after he was found unconscious with “mucus-type liquid coming out of his nose and mouth.” He’s reportedly in critical condition but breathing.  Khloé Kardashian is said to be by his bedside, along with her sister Kim Kardashian West and Kardashian matriarch Kris Jenner.

Drugs and alcohol are not said to be factors, although the former “Khloé and Lamar” star did order a bottle of cognac when he arrived and was allegedly using herbal Viagra. TMZ reports that “a third of the bottle” was left when he was found unconscious. Sources added that he was “popping 8 to 10 herbal Viagras at a time” prior to being found in his VIP room.

According to TMZ, Odom is in a coma and his heart is failing.
