Kylie Jenner and her older half-sister Kourtney Kardashian are the latest family members to publicly comment on Lamar Odom's medical crisis. The reality TV stars both shared photos of Odom, their brother-in-law, on their respective Instagram accounts Thursday, asking fans to pray for the former basketball player.

Alongside an image of herself and Odom with their hands in the air, Kylie wrote, “Let’s dance again together soon. Prayers up for Lamar, please.” She also posted a video of the former Los Angeles Lakers player doing the stanky leg at a party. Kourtney shared a picture of the 35-year-old athlete playing with her 5-year-old son, Mason, writing, “Believing in the power of prayer for this beautiful soul.”

Kylie and Kourtney's posts came shortly after TMZ reported that the athlete's condition had "deteriorated." The site wrote that doctors informed Odom's family the longer he stays hooked up to machines, the less likely it is he will regain consciousness.

It's been reported that Khloé Kardashian has the difficult task of making medical decisions for Odom because she is still legally married to him. Khloé filed for divorce from Odom in December 2013, but it was never made official.

As previously reported, Odom was rushed to Sunrise Hospital & Medical Center in Las Vegas Tuesday after he was found unconscious at Love South Ranch, a legal brothel in Pahrump, Nevada.

The athlete is surrounded by his friends and family, including the entire Kardashian family -- minus Rob Kardashian -- as well as his children Destiny; Lamar Jr. his father, Joe Odom; and his ex-fiancée Liza Morales. According to E! Online, Khloé had Odom's kids and ex fly out to the hospital to be by his side.

Shortly after news broke of Odom's hospitalization, Kylie's sister Kendall Jenner sent out a somber tweet saying, "please don't go." Their half-brother Rob Kardashian and mom Kris Jenner have also reached out to fans asking for prayers.
