The former Disney star, who's well known in Hollywood for being better than most when it comes to signing autographs, was posing with fans in the tropical nation when boyfriend Liam began pulling her away. It was then an angry member of the crowd yelled at Miley, calling her an "a------."
That word didn't sit well with Miss Cyrus, who stopped dead in her tracks and turned around to address the hater. "What the f---? Are you serious?!" Miley swore back. It took a gentle grab of the arm by boyfriend Liam to snap Miley back to reality and the two walked quickly away together.
