On Tuesday, Mariah Carey was spotted being pushed around in a wheelchair at Los Angeles' LAX Airport.

What gives?

"Mariah twisted her ankle in Singapore and should have packed more sensible shoes, but she doesn't have any," her rep, Cindi Berger, tells "I'm sending her a pair of flats today."

The singer, 41, recently took a spill on stage in the country.

Earlier this summer, rumors swirled that she is pregnant, but she has never confirmed them.

"I appreciate everyone’s well wishes. But I am very superstitious," she coyly wrote on her website last month. "When the time is right, everyone will know – even Cindi Berger."
