Justin Timberlake DWI Arrest Police Body Cam Video Released

Here's the police body cam from Justin Timberlake's DWI arrest in Sag Harbor, NY ... and it shows him struggling through sobriety tests, and his friend playing the *NSYNC card.

The video of the June 2024 arrest was finally released late Friday, revealing cops gave JT a series of field sobriety instructions ... some of which seemed to confuse him. At one point Justin says, "These are, like, hard tests."

Justin was extremely polite as the officer shined a flashlight in his face to observe his eyes, and told him to look straight ahead. Once they tell Justin to walk a straight line, he stumbles a few times.

He eventually paused and said, "My heart's racing."

Then comes the moment police put him in handcuffs, just as Justin's female friend -- he had been out with her and her husband that night -- shows up on the scene and offers to drive Justin's car.

While Justin didn't resist arrest, his friend was apoplectic about officers taking him into custody ... asking, "You're arresting Justin Timberlake right now??!!"

When she asks the officers if she can give Justin his phone, they tell her that's against the rules, and that's when she dropped his *NSYNC creds.

She begs them, "Can you guys please just do me a favor 'cause you loved 'Bye Bye Bye' or 'Sexyback?' Do me one favor!"

Lo and behold ... it worked. They allowed her to briefly speak to Justin as he sat in the back of the police car, before taking him to the station. As he sat behind the cage of the officer's car, Justin asked why they're arresting him.

As we reported, Justin sued earlier this month to stop the body cam release, claiming the footage was "an unwarranted invasion of personal privacy."

He's since changed his tune on that, because on Friday Sag Harbor PD announced they came to an agreement with Justin to release a partially redacted version of the video.

As you know ... Justin was arrested on suspicion of DWI ... resulting in his viral mugshot and plenty of "ruin the tour" memes. An anonymous source claimed JT had said that to the arresting officer, but we don't see him say it during the 18-minutes of footage.
