Chris Kirkpatrick took to Instagram to shower praise on Timberlake, who revealed Thursday that he was diagnosed with the debilitating disease.

"I've been battling some health issues, and was diagnosed with Lyme disease," Timberlake wrote. "If you've experienced this disease or know someone who has," he added, "then you're aware: living with this can be relentlessly debilitating, both mentally and physically."

Justin Timberlake is "not doing s---" as he relaxes at home, following the end of his two-year Forget Tomorrow World Tour and his Lyme disease diagnosis. He shared the life update in an Instagram Stories photo posted on Aug.
