Mariah Carey has been spotted at Los Angeles International Airport in a wheelchair after suffering a fall.

The singer was performing in Singapore last weekend when her stiletto shoes caused her to tumble on stage and hurt her ankle, reports E Online.

"Mariah twisted her ankle in Singapore and should have packed more sensible shoes, but she doesn't have any," said her rep Cindi Berger.

"I'm sending her a pair of flats today."

Carey laughed off the incident on Sunday via her Twitter page, writing: "TY SO much to my fans in Singapore!!! Yeah, several hectic moments, (lol!) but I tried to swirl them into festive!

Mariah Carey falls on stage

Mariah Carey has fallen on stage during a gig in Singapore.

The singer - rumoured to be pregnant - was performing to over 100,000 guests at the Formula 1 Singtel Singapore Grand Prix event yesterday.

In a YouTube clip, the 'Obsessed' star is seen singing her hit song 'Make It Happen' when she slips over in her stiletto heels.

Carey was then caught by one of her backing dancers as she told the crowd: "Hold up, I want someone to help me take these shoes off. I wasn't supposed to be wearing them!"

She then continued singing while ushering her assistant to come out on stage and help her remove the shoes.

Carey, who sang a string of her biggest hits at the event, including 'Dreamlover, 'My All' and 'Hero', recently said that she will announce her pregnancy "when the time is right".
