Kim Kardashian is in the home stretch of her second pregnancy, and she has revealed the exact amount of weight she has gained carrying her unborn son. The "Keeping Up with the Kardashians" star said that she has gained 52 pounds and only has six to go before she gives birth for the second time.

"Ok I'm 52 lbs up today....and I still have 6 weeks to go! I got my work cut out for me!!!!" Kardashian wrote on Twitter.

The wife of Kanye West previously announced that her son would be born on Christmas Day and that they have booked a deluxe maternity suite at Cedars Sinai Hospital in Los Angeles, as HNGN previously reported. Kardashian has a health condition where the placenta grows too deeply into the uterus. This condition could potentially be extremely dangerous, and doctors plan on delivering the baby naturally on Christmas. Depending on her condition, a C-section may be necessary for health and safety reasons, as her 2-year-old daughter North West was born a month early.

It is no secret that the reality star had a rough first pregnancy where she gained about 50 pounds, the Daily Mail reported. Kardashian has been open with her weight gain and opened up about her struggle on her website.

"I'm gonna keep it real: For me, pregnancy is the worst experience of my life! LOL," Kim wrote on her website, according to Jezebel. "I don't enjoy one moment of it and I don't understand people who enjoy it. My mom and Kourtney clearly did! More power to them, but I just don't relate!"
