Here’s Bruno Mars in a state of nirvana … he’s performing one of Nirvana’s biggest hits … and it’s all on video.

Check out this clip from Thursday’s private show at the Capitol Theatre in Port Chester, NY … Bruno is on stage with Slash, Duff McKagan, and Chad Smith when they start playing Nirvana’s 1991 classic, “Smells Like Teen Spirit.”

Bruno’s into it, and so is Orlando Bloom … he’s the cameraman here who recorded the video and shared it on his Instagram story. Thanks, Orlando!

Eddie Vedder, Anthony Kiedis, Brandi Carlile, and Yungblud also hit the stage for the exclusive event — a show put on by Eldridge Industries — and they blended pop, punk, grunge, and classic rock in an epic jam sesh.

Ring the opening jingle bells … because this holiday season brought out the worst in a group of Nantucket shoppers — leading to a brawl in the streets!

Video taken over the weekend is now circulating online … and it kicks off with a group of people in an argument outside the Nantucket Christmas Stroll, an annual outdoor market complete with a tree lighting and visit from Saint Nick himself.

After some pushing, pulling, and arguing, all hell breaks loose when someone appears to throw a punch — and another guy jumps on his back to stop him.

According to local outlet Nantucket Current … police responded and began investigating — but, as of Sunday, no one has been arrested in connection with the fight yet, though we’re sure they’ve now made Santa’s naughty list for this one.

Chuck Potthast‘s son apparently found his body … and he told the 911 operator his dad was bleeding heavily — and didn’t look alive.

We’ve obtained the audio of the 911 call … which begins with a man identifying himself as Chuck’s son — and telling the 911 operator his father’s lying in the bathtub and bleeding from the chest.

Potthast’s son says he doesn’t know what happened to his father … and, when the operator asks him if he’s awake, he responds by saying he doesn’t think Chuck even looks alive.

As you know … Elizabeth Castravet — Potthast’s daughter who also appeared on ’90 Day Fiancé’ — announced her father’s death last month, posting on social media that the whole family’s “devastated” after the loss. His other daughter, Rebekah Lichtwerch, paid tribute to their father as well by writing that her world has been “distorted into a place I don’t understand.”

Chuck was open about his health struggles in recent months … posting in September about an 8-hour surgery he underwent to repair a hernia and a collapsed stomach. It’s unclear if these same health issues played a role in his death.

Potthast was 64.
