Lil Nas X Strips Down Nude Before Arrest, See Video

You might want to hold onto your undies for this one — Lil Nas Xwas spotted completely naked before his arrest this week … and we’ve got video of the stunning moment.

Check out our clip — he’s strolling down the street while singing after ditching his underwear and boots somewhere in Los Angeles. He seems completely unfazed by his lack of cover … even making eye contact with the camera as he puts on a show.

And if you didn’t notice … he’s belting some Nicki Minaj lyrics, specifically her line in “Monster” by Kanye West.

We’re told he was spotted running free around 5:45 AM Thursday, not long before police picked him up and had him transported to a hospital for a possible overdose.

TMZ learned bystanders had reported to LAPD that they saw a nude man walking down the road prior to his arrest … and now, we see their reports were accurate.

We also obtained footage of the “Old Town Road” hitmaker before he lost his undies … strutting down Ventura Blvd at 4 AM in his underwear and matching cowboy boots, warning the folks behind the camera not to miss the party.

At one point, he confidently belted out some bars … and then placed a traffic cone on his head during another part of the bizarre clip.

Lil Nas was eventually transported from the hospital to a jail cell on Thursday … and we broke the news Friday that Lil Nas must stay behind bars until Monday.

We’re told he was arrested on suspicion of battery on a police officer … so he needs to face a judge to have his bail set — which won’t be until at least Monday.
