Justin Timberlake Not ‘Under The Influence’ In Viral Resurfaced Concert Video

Justin Timberlake was not intoxicated or otherwise under the influence during a concert last month — this despite the internet thinking they found a gotcha clip … TMZ has learned.

Sources with direct knowledge tell TMZ … a resurfaced viral video that appears to show JT looking what some have suggested is “under the influence” or out of sorts is simply being over-analyzed way too much by folks looking to unfairly condemn the guy.

While online trolls have said Justin looks out of sorts in this clip — which was filmed and posted in May during one of his Vegas concerts, and which has since gone viral in the wake of his DWI arrest — our sources tell us he wasn’t even close to that state of mind.

Our sources say JT is always focused and clear-headed at all his shows — including all the ones he’s performed at while on tour lately — and the one from May is no exception … despite what people *think* they see in this footage.

We’re told that, as a performer, you’d have to be sober doing what he does … there’s simply too much at stake in the performance.

As you know, all eyes have been on JT after his arrest last week … where he was pulled over in Sag Harbor, NY for allegedly blowing past a stop sign and swerving on the road.

The *NSYNC alum addressed the legal drama at his Chicago show this past weekend, telling the crowd … “It’s been a tough week, but you’re here and I’m here, and nothing can change this moment right now.”

His lawyer has indicated they plan to fight the charge, however … with the attorney telling TMZ he plans to “vigorously” defend the singer, who has a court date on July 26.
