<p><br /> Mariah Carey has taken a tumble during a concert in Singapore.<br /> </p><p><br /> It happened as the 40-year-old singer belted out her song Make It Happen at a Formula 1 event.<br /> </p><p><br /> She was quickly helped up by two of her dancers and Mariah dealt with the incident in good humour quickly saying: "I did that on purpose."<br /> </p><p><br /> Marah then added: "Someone come out here and take these shoes off!"<br /> </p><p><br /> Two assistants then rushed onto the stage to help undo what appeared to be very complicated fastening on her high heels and Mariah finished the ninety-minute performance barefoot.<br /> </p><p><br /> Mariah later tweeted: "TY SO much to my fans in Singapore!!! Yeah, several hectic moments, (lol!) but I tried to swirl them into festive!.Love+ God Bless!"<br /> </p>
