Reports suggest "The Stronger" hitmaker is receiving treatment for exhaustion and sleep deprivation at the University of California, Los Angeles (UCLA) Medical Center.
He was admitted on Monday hours after his representatives cancelled the remaining dates on his Saint Pablo Tour, and many celebrity friends and fans flocked to social media to send their support and prayers to Kanye.
Now DMX has added his thoughts in a video posted to Instagram.
"I wanted to give a special shout-out to Kanye," he said in the video.
DMX has struggled with his own mental health issues in the past and has spoken about his battle with bipolar disorder and substance abuse.
