(CNN) Singer Rod Stewart has been charged with simple battery after punching a security guard at the Breakers Hotel in Palm Beach, Florida, on New Year's Eve, police say.

Stewart, 74, told police he and his family were trying to get the children in their group access to a private event at the hotel, according to a Palm Beach Police Department probable cause affidavit obtained by CNN affiliate WPTV

The security guard working the event in the children's area said Stewart's group was unauthorized to enter and asked them to leave after they "began to get loud and cause a scene," the affidavit states.

Stewart's son, Sean Stewart, then "got about 'nose to nose' distance" from the security guard's face, police said. The security guard placed his hand on Sean Stewart's chest and asked him to give him space when Sean Stewart shoved him backward.

Rod Stewart then punched the security guard in his left ribcage area, police said.
