Reality TV star Kim Kardashian "doesn't feel great" during her second pregnancy.

"She might look amazing, but she doesn't feel that great," a family source told eonline.com on Wednesday.

"She is often uncomfortable. That being said, she feels much better this time around than she did with North," the source added.

Kim, who has worn a number of stylish maternity looks in recent months, and Kanye are expecting a baby boy, who will join big sister North West, 2. The reality star is due to give birth in December.

Kim had contracted laryngitis toward the end of her first trimester.

"So f--king sick today on all levels!!!!! UGHHHHHHHHH I can't deal!!!!!!!!!! Praying I get through the day!," Kim had tweeted.
