The 35-yr-old actor model Kim Kardashian reveals how she's staying fit in the last trimester of her pregnancy.

Kim Kardashian, who is expecting her second baby with husband Kanye West, revealed that she is feeling 'as fat as fAAk' and her soon-to-be-born son is the size of a pumpkin.

The Keeping Up with the Kardashians star also mentioned that these days she has to eat Lay's Barbeque-flavoured potato chips, News.com.au reported.

The 35-year-old reality star was recently spotted in Givenchy flip-flops and shell-toe sneakers to comfort her swollen feet as her dainty ankles are no longer easily sliding in and out of pumps.

Kardashian's due date is around Christmas Day.
