Michael Jackson reportedly has landed in Las Vegas, returning to the United States to try and revive his music career.

Jackson nearly sparked a riot during a shopping spree at Caesars Palace, the New York Post reported, with hundreds of tourists following the singer, who was wearing dark pants, a white shirt and a black leather jacket, and three hotel security guards.

"He's amazing. His moves, his music. He's unique. He's a legend," said one fan, Los Angeles resident Natalie Natalynorohian.

Another woman, Cathy Bamshad, admitted she has liked Jackson since she was a little girl.

"When I was a child, I had Michael Jackson posters, Michael Jackson sweaters, everything was about MJ," she said.

"Yes, he's here, and yes, we're working on projects. But we're not willing to disclose anything," businessman and friend Jack Wishna said.
