It's the latest publicity-making turn of events as "The Born This Way Ball" travels through Asia. Lady Gaga's provocative lyrics and costumes have angered Christian groups in South Korea and the Philippines and Islamists in Indonesia, where the show may be banned.
Now she is stirring nationalist fervor in Thailand, where people tend to get upset when the country's seedy underworld is highlighted by outsiders.
Lady Gaga posted her tweet shortly after her private jet arrived Wednesday night: "I just landed in Bangkok baby! Ready for 50,000 screaming Thai monsters. I wanna get lost in a lady market and buy fake Rolex."
"We are more civilized than you think," tweeted Thai DJ Surahit Siamwalla, who has a ticket to Friday's show in Bangkok but said he plans to boycott.
"She came to our home, but instead of admiring us she insulted us," said a commentator on popular Thai web board pantip.com.
It is unclear what a "lady market" is but some Thai fans assumed she meant the popular outdoor Ladies Market in Hong Kong, where she already toured - and also eyed the luxury knockoffs.
