Mariah Carey took a spill while performing at a show in Singapore this past weekend, and is now wheelchair-bound, according to photos taken of Carey at the Los Angeles airport this week.

The Grammy-winning singer, who is rumored to be pregnant, was seen wheeling around LAX on Wednesday, but her rep claims that Carey merely took the wheelchair because she had the wrong shoes. "Mariah twisted her ankle in Singapore and should have packed more sensible shoes, but she doesn't have any," her publicist explained. "I'm sending her a pair of flats today."

Although she took a pretty hard spill during her performance, Carey still managed to send out a post-show tweet to acknowledge and thank her Singapore fans. "TY [thank you] SO much to my fans in Singapore!!! Yeah, several hectic moments, (lol!)but I tried to swirl them into festive!.Love+ God Bless!" she wrote.

Meanwhile, both Carey and husband Nick Cannon have been evasive regarding her rumored pregnancy. "I've said it before and I'll say it time and time again -- when my wife feels like talking about whatever she wants to talk about, you will hear it directly from her," Cannon told Us Magazine. "We all know it's extremely personal, and it is for a woman to deal with things with her body, and especially when dealing with the idea of childbirth and all that stuff."
