Agence France-Presse was among news outlets to report that police briefly held the heiress Saturday after she arrived at the airport in Figari on a private jet from Paris. The report, which cited police sources, said police found less than a gram of cannabis in Hilton's handbag and that she was soon released without charge.

"So sick of people making up rumors about me," Hilton tweeted in her defense Saturday. "The latest one about me is completely false too. Don't believe what you read. Silly nonsense."

Hilton later added: "The stories saying I have been arrested are completely false! I am having the best vacation of my life!"

Hilton was recently detained in the South African city of Port Elizabeth during the World Cup on suspicion of possession of marijuana. The case was later dropped and no charges were filed.
