"It's worth noting that Tommy Lee requested no prosecution relating to the incident, and there were no injuries to either person," said Dan Kulin, a spokesman for the Clark County (Nev.) District Attorney, David Roger.
"The Clark County district attorney's office will not pursue charges against Robert James Ritchie, also known as Kid Rock, involving a confrontation with Tommy Lee on September 9, 2007, at the Palms Hotel and Casino," Roger said in a statement.
Reps for Kid Rock and Lee didn't respond Tuesday to requests for comment. Both are ex-husbands of Pamela Anderson.
Kid Rock, 36, wasn't taken into custody, but was cited for battery after he was accused of slapping and punching the 45-year-old Motley Crue drummer.
Witnesses said that although Kid Rock threw the only blows that landed, Tommy Lee appeared to have started the confrontation, which occurred in the audience.
His problems aren't over, though. Kid Rock also faces a misdemeanor battery charge stemming from an October 21 Waffle House brawl in Atlanta. He and his entourage were cited after a brawl with a male customer broke out at a restaurant.
