Oh, my.  Even Kim Kardashian‘s  gym clothes are wardrobe disasters these days!

The pregnant reality star’s famous rear was the bump most painfully noticeable in what should have been a slimming outfit.

Her baby bump — and as RadarOnline.com reported, she’s expecting a girl — is still barely showing.

The Kourtney & Kim Take Miami  star stayed with the all-black look when she attended a photo exhibit at a West Hollywood gallery Saturday night, but our eyes are still burning from how she looked in those gym clothes.
