Perhaps Kim Kardashian was concerned that her recent maternity wear choice of, you know, actual maternity wear wasn't sexy enough.

The pregnant reality star stepped out in a very clingy black dress and open-toed stilettos in Los Angeles Monday, and was caught on camera sporting the flashy ensemble while performing a decidedly less glamorous task: pumping gas.

The expectant mom, 32, hasn't let pregnancy slow down her jet-set lifestyle with boyfriend Kanye West, but was reportedly told by doctors to dial it back after she fell ill on a flight from Paris last week.
