New footage appears to show Nolan Wells partying with his friends on the Fourth of July — and could be the last time he was seen on camera before he was mysteriously found dead days later, according to TMZ.

A black man who appears to be Wells, 18, can be seen bending over on the back of an anchored boat, possibly to grab a drink, in a short video clip obtained by the outlet that shows revelers celebrating the holiday on Horn Island off the Mississippi coast the day he vanished.

The man in the video, whose face is not visible, appears to be wearing light-blue swim trunks similar to the ones Wells was photographed wearing earlier in the day.

The person who snapped the video felt confident enough that it could be Wells that he turned it over to investigators probing the college football player’s death, the outlet reported.

The metadata on the footage reportedly shows the video was recorded around 2:23 p.m. on July 4. He was last seen on the island around 3 p.m. talking to a girl.

GPS data from the boat Wells arrived on at the popular barrier island with his pals shows the vessel left around 4:30 p.m., NBC News reported. Police said Wells’ friends traveled back without him.

“From what we understand, he chose to stay there,” Jackson County Sheriff John Ledbetter previously told ABC News.

The Post has reached out to Wells’ family’s lawyer, civil rights attorney Ben Crump, for comment on the new footage.

The teen’s body was found in the water off Horn Island on July 6.

Police have said nothing points to foul play, at least yet, and they suspect Wells likely drowned. They are awaiting official autopsy results.

Here’s the latest on the disappearance and death of Mississippi teen Nolan Wells:

• Nolan Wells vanished near currents known locally as the ‘washing machine,’ a Cajun Navy leader claims
• Mississippi gov blames activists in Nolan Wells case for ‘stoking division’

But Wells’ family is conducting an independent investigation amid what they claim are inconsistencies surrounding the teen’s death.

Wells’ body also underwent an independent autopsy — paid for by ex-NFL quarterback Colin Kaepernick. The preliminary findings of that will be announced Wednesday morning, Crump has revealed.

The video emerged a day after Wells was laid to rest in his hometown of Ocean Springs in an emotional closed-casket ceremony attended by his grieving mom and dad, Rev. Al Sharpton, famed director Spike Lee and former NFL wide receiver Terrell Owens.

Crump on Monday led mourners in chants of “Justice for Nolan Wells!” and “Nolan’s life matters!”

“We are on a ferocious search for the truth, the whole truth and nothing but the truth, so help me God,” he said at the service.
