Jimmy Fallon Just Revealed This Shocking Bombshell About His Covid Battle—So Sad!

"Thank you to the doctors and nurses who work so hard around the clock to get everyone vaxxed" he continued. "Thank you to NBC for taking the testing protocols so seriously and doing a great job - and also thanks for putting me in the “What ‘chu talkin’ about Willis?” isolation room when they told me the news."

Many celebrity friends commented on his post with well wishes, including Reese Witherspoon (who recently appeared on his show) writing: "Hope you had a speedy recovery!" and Kristen Chenoweth who commented, "Jimmy please rest. Eat. Repeat. Feel better," followed by a red heart emoji. And it looks like those wishes helped, as the talk show host revealed that he is "feeling 100%" when asked by a fan on the same post when he would be returning to The Tonight Show. On January 4th, Jimmy said: "The positive came back on 12/18. Back at work today and feeling 100%!"
