MIAMI — Rod Stewart has certainly had better New Year’s Eves.

There was the one 41 years ago when the British rocker — and current South Florida resident —opened 1979 with one of his signature smashes, “Da Ya Think I’m Sexy?”

He was knighted in late 2016 at Buckingham Palace, which assuredly added luster to the 2017 New Year.

But New Year’s Eve 2019/2020 will go down as one the pop star probably would like to forget.

Stewart, who turns 75 on Friday, and his 39-year-old son Sean Roderick Stewart, were each charged with simple battery by the Palm Beach County Police Department.

Police say father and son got into an altercation on Tuesday night with a man who was working as a security guard employed by the Breakers Palm Beach resort for a private event in a children’s area.

According to the probable cause affidavit, the guard, Jessie Dixon, 33, saw a group of people approaching the check-in table, but they were not authorized to be there.

The group — which included Stewart and his family — started “to get loud and cause a scene” and refused Dixon’s demands that they leave. That’s when Stewart’s son Sean “got about nose to nose distance” from the security guard’s face, according to the report.

Police say the younger Stewart shoved Dixon backward after Dixon put his right hand on Sean’s chest and told him he needed to back up and give him some space.

That’s when Rod — identified on the arrest report by his full name, Roderick David Stewart — stepped forward and threw a punch at the security guard, hitting Dixon in his left ribcage area, according to the affidavit.

Two Breakers employees who were working the private event — Olivia Pace, 18, and Kaylyn Viteri, 22 — told police they saw Sean push Dixon and Rod punch him in the chest with a closed fist.

Police say surveillance video “revealed both Sean Stewart and Rod Stewart as the primary aggressors.”

According to the affidavit, Rod Stewart told officers that his group had approached the check-in table so the children that were with them could gain access to the event.

When Dixon denied the Stewart clan access, Rod told police the guard became argumentative with his family and that this made them “agitated.”

“Rod Stewart apologized for his behavior in the incident,” the affidavit said.

Rod and Sean Stewart were issued a notice to appear at the Palm Beach County Criminal Justice Complex on Feb. 5, 2020.

Stewart has homes in London, Beverly Hills and on South Ocean Boulevard in Palm Beach County.

In a 2015 interview with the Miami Herald, Stewart called the Florida home “my favorite place to be.”

He’s even recorded some of his biggest hits in South Florida, including the controversial and misunderstood disco-rock classic, “Da Ya Think I’m Sexy?” Others include “Tonight’s the Night,” “You’re in My Heart (The Final Acclaim)” and “Hot Legs.”

Those late-1970s hits and their parent albums — “A Night on the Town,” “Foot Loose and Fancy Free” and “Blondes Have More Fun” — were produced by Tom Dowd and partly recorded at North Miami’s Criteria Studios.
