Mariah Carey stumbles in VERY high platform heels on red carpet

Mariah Carey  stumbled on the red carpet in her  very high platform heels on Monday. 
 The singer, 46, lost her shoe after tripping up in her Louboutins at the NBC Upfronts in New York City, where she is promoting her upcoming reality show. 
The star, who was dressed in a tiny animal print sequined dress and fishnet stockings, quickly grabbed onto her security guard and managed to regain her balance.
