What happens in Vegas does not always stay in Vegas.

Video of Justin Timberlake performing with bloodshot eyes at a Forget Tomorrow World Tour show in Sin City last month has gone viral following his DWI arrest earlier this week.

In the footage first posted via TikTok in May, the 43-year-old pop star is seen walking across the floor of the T-Mobile Arena as he passes excited fans with his backup dancers in tow.

The camera shot then pans closely to his face, making it hard to miss his eyes, which appear opened wide and bloodshot.

Fans immediately flooded social media with comments about the “Mirrors” singer’s appearance, with one concerned X user writing, “He looks wrecked. Get help bro.”

“Those eyes though… dude is either not slept in a week or is going for round 2,” another fan theorized.

A third person added, “he doesn’t look okay……..”

Several others mocked him by saying the video would “ruin the tour,” reiterating what Timberlake allegedly told a young police officer who did not recognize him during his arrest.

A source previously claimed to Page Six, “Justin said under his breath, ‘This is going to ruin the tour.’ The cop replied, ‘What tour?’ Justin said, ‘The world tour.’”

Despite his concerns, the “SexyBack” hitmaker took the stage without a hitch in Chicago Friday night for his first post-arrest performance.

Although Timberlake rocked the stage, he admitted to fans that his week had been “tough.”

He added at the time, “I know I’m hard to love sometimes but you keep loving me right back.”

Timberlake was arrested and charged with driving while intoxicated Tuesday after getting pulled over by a rookie cop, who has been identified as “over-aggressive” officer Michael Arkinson.

The “Rock Your Body” singer was also given citations for running a stop sign and failure to stay in a proper lane of travel.

According to the criminal complaint, Timberlake insisted at the time that he only had a single martini to drink that evening and refused to take a breathalyzer test.

However, Arkinson noted in the report that the *NSYNC member “performed poorly on all standardized field sobriety tests,” had “bloodshot and glassy” and smelled of alcohol.

After the arrest, a person close to the 10-time Grammy winner told Page Six Timberlake had cut out booze from his diet ahead of the world tour and was living a healthier lifestyle.

Another insider, though, said it’s “not a secret” that he has a drinking problem.
