Kim Kardashian gains four cup sizes during pregnancy; flaunts low cut vest at the gym

Kim Kardashian conquers pregnancy curves, sporting a stunning gym look with four cup size gain.

Thirty one year old reality TV star Kim Kardashian was spotted at her gym in LA where she flaunted a black workout outfit with a low cut vest that showed off her ample curves. Kim is four months pregnant with her first child with rapper boyfriend Kayne West, and is due in June. She is said to have gained four cup sizes, and has gone from a 36D to a 36G, although she is just in the second trimester of her pregnancy and sure seems like the most miserable mother-to-be-ever. We have hardly seen her blushing with joy, and she is regularly seen making trips to the gym. Not happy with the baby weight, Kim? Or was the baby not a mutual decision?
