As Lamar Odom continues to fight for his life in a Las Vegas hospital, Kris Jenner and Rob Kardashian — who became family members with the former NBA star when he married Khloe Kardashian in 2009 — are asking for prayers on social media.

On Wednesday night, Jenner posted an Instagram photo of Odom during his Los Angeles Lakers days, with the caption, “Please pray for Lamar #ourfighter.” Soon after, Kardashian posted his own Instagram of himself and Odom in happier times. “Praying nonstop for my Brother !!” reads the caption.

Kendall Jenner also posted this cryptic tweet on Wednesday morning:

Odom, who was found unconscious in a Nevada brothel on Tuesday afternoon, remains in critical condition at Sunrise Hospital in Las Vegas. According to Us Weekly, wx-wife Khloe Kardashian, whom Odom divorced in 2013 after four years of marriage, has been at her ex-husband’s side overnight. Odom’s ex-wife Liza Morales and children Destiny and Lamar Jr. were flown in to Las Vegas on Wednesday to join members of the Kardashian-Jenner family.

It was confirmed on Wednesday that Odom had used cocaine when he first arrived at the Love Ranch South in Crystal, Nev. last weekend. Odom received three years’ probation after pleading no contest to a DUI charge in 2013.
