On Friday night, I watched a little bit of Rocky Balboa on cable. That’s the one from 2006, when Sylvester Stallone was 60. Rocky gets into the ring one last time to take on the much younger heavyweight champ and gives him the toughest fight of his life. At 60. Then I saw this headline: Rod Stewart and Son Charged with Battery in Palm Beach Brawl. As hard to believe as that might be, it’s true. The 74-year-old singer and his 39-year-old son, Sean, assaulted a security guard at The Breakers resort on New Year’s Eve.

According to a criminal affidavit, when Rod and Sean Stewart were denied entrance to a private event that was being held in “a children’s area” of the resort, they “began to get loud and cause a scene … and refused to follow instructions to leave.”  The father-and-son team then assaulted a security guard. Sean, 39, reportedly shoved him before Rod, 74, punched him in “the left rib cage area.” Whoa, Rod!

Police say that although neither was taken into custody following the altercation, each Stewart has been charged with simple battery. The Stewarts are due in a Palm Beach court on February 5th. Do you think Rod will try to play the “I’m just an old man” card? That might be tricky for the guy who sings “Forever Young.”
