Post Malone's fans are worried about him after a video of him stumbling and rolling his eyes during a performance circulated on the internet.

Many believe Post is struggling with drugs and alcohol and may soon die.

Post pushed back on that during his Runaway tour stop at the FedExForum in Memphis, Tennessee last night.

"I'm not on drugs. I feel the best I've ever f*cking felt in my life," Post said. "And that's why I can bust my ass for these shows and f*cking fall on the floor and do all that fun sh*t. But for anyone that's concerned here, I appreciate the love and the support, but I feel f*cking fantastic and I'm not doing drugs."

You think Post is gonna be OK?

post malone has been acting strange and inebriated at his shows. ppl are fearing that this behavior is from drugs and alcohol. even if you don’t like post malone pls don’t cheer this on. he clearly needs help and ignoring it only leads to tragedies. remember amy winehouse. pic.twitter.com/8L428HzVQr
