A plea deal between Sir Rod Stewart and Florida prosecutors has collapsed, which means he and his adult son must again face trial for attacking a security guard at a New Years party nearly two years.

Neither Sir Rod nor his son Sean were present when Judge August Bonavita announced that a hearing in which a deal was to be finalized was called off.

The pair are now due to stand trial for battery charges on January 25.

This is at least the second time that a deal has failed in this deal, which has also been delayed by the coronavirus pandemic.

The Stewarts face a maximum sentence of one year in prison, although such a long sentence is unlikely.

Neither prosecutors nor defense attorney Guy Fronstin immediately responded to calls and emails seeking comment.

The Stewarts had an argument at the Breakers Hotel with security guard Jessie Dixon on December 31, 2019, shortly before midnight, police said.

They said the Stewarts were part of a group who tried to enter a private event in a children’s area at the posh hotel, but were not allowed.

The group, which included children, created a scene and did not want to leave, police said.

Dixon stepped in and Sean Stewart, 41, “stood in front of him,” according to the police report.

Dixon told officers he put the back of his right hand on young Stewart’s chest and asked him to step back. A security video showed Sean Stewart pushing Dixon and Sir Rod, 76, hitting him in the ribs.

Sir Rod is a member of the Rock and Roll Hall of Fame. Her biggest hits include Maggie May, Do Ya Think I’m Sexy? and the night of this evening.

He was knighted in 2016.
