Rob Kardashian and Kris Jenner post heartbreaking messages for Lamar Odom

Kendall Jenner isn't the only member of the Kardashian/Jenner family to take to social media in support of Lamar Odom, who remains in the hospital. Rob Kardashian broke his three-week Instagram silence to post this emotional message for Lamar on Wednesday.

He wrote:

Praying nonstop for my Brother !!

Episodes of Keeping Up with the Kardashians and Khloe & Lamar showed that Rob and Lamar had a very close relationship when Rob lived with his sister, Khloe Kardashian, and the former NBA star.

Mama Kris Jenner also took to Instagram and asked fans for their support. She captioned a pic of a happy Lamar on the basketball court in his L.A. Lakers uniform:

Please pray for Lamar #ourfighter

She also included a prayer hands emoji in her post.
