Kourtney Kardashian and Kylie Jenner have broken their social media silence about Lamar Odom‘s hospitalization.

Jenner, 18, took to Instagram to post an old black-and-white photo of her and Odom dancing in a car together.

“Let’s dance again together soon,” she wrote as the caption on Instagram. “Prayers up for Lamar please.”

The post marks the first time Jenner has spoken out since she abruptly ended her live stream on Tuesday after learning the news.

Jenner also shared a video of Odom dancing and doing the “stanky leg.”

“Stanky leg soon..” she wrote.

Kardashian, 36, also took to Instagram to share her prayers, posting an old picture of the former basketball star and her son Mason, now 5.

“Believing in the power of prayer for this beautiful soul,” she wrote.

Odom, 35, is in a coma at Sunrise Hospital in Las Vegas, where he was rushed to after being found unconscious at a Nevada brothel Tuesday afternoon.

The former NBA player had cocaine and opiates in his system, sources told PEOPLE.

Also on Thursday, Jenner’s boyfriend Tyga, 25, shared his own Instagram post in support of Odom: “Stay strong bro. We all praying for you champ. God Got a plan for you.”

Kris Jenner, Kendall Jenner and Rob Kardashian and several celebrities have also shared prayers for the former NBA star.

The famous family, with the exception of Rob, has gathered in Las Vegas for Odom. Odom’s estranged wife Khloé Kardashian, 31, has not left Odom’s side since flying in Tuesday night, sources told PEOPLE.

She is also in charge of Odom’s medical care as the two are still legally married despite having split two years ago.
