The reality star, 29, was questioned by police Friday in Port Elizabeth for allegedly smoking marijuana at the World Cup. Hilton was briefly detained outside the Nelson Mandela Bay stadium, where she had been watching the World Cup quarterfinal match between Brazil and the Netherlands.
But a rep for Hilton says she's been cleared of any wrongdoing.
"The incident was a complete misunderstanding and it was actually another person in the group who did it," the rep says. "The case has been dropped against Paris and no charges will be made. The authorities have apologized for wrongfully accusing her since she had nothing to do with the incident."
The rep adds that Hilton is "having an incredible time at The World Cup and looks forward to going on a safari this week.”
The heiress's latest legal trouble comes three years after she went to jail for violating probation in an alcohol-related driving case.
