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."

Timberlake, 44, opened up about his "debilitating" Lyme disease symptoms after coming under criticism for his tour performances.
