"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, spokesman for Clark County District Attorney David Roger.
Representatives for Kid Rock and Lee didn't immediately respond Tuesday to requests for comment. Both are ex-husbands of Pamela Anderson, who was a presenter at the show.
Kid Rock, 36, wasn't taken into custody, but was cited by police for misdemeanor 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, Lee appeared to have started the confrontation, which occurred in the audience.
Kid Rock faces a misdemeanor battery charge stemming from an Oct. 21 arrest in Atlanta. He and five members of his entourage were cited after a brawl with a male customer at a Waffle House restaurant.
