Reality TV star Kim Kardashian West's second child with her husband Kanye West is due in December.

Kim, who already has a 23-month-old daughter North with Kanye, confirmed she was pregnant earlier this week.

She is expecting to give birth in December, a source told eonline.com.

It is also thought that the family could have two more members by Christmas after sources close to the star revealed she is expecting twins.

While Kim has been open about her struggle to conceive for the second time after undergoing IVF, it has since been reported she is having a double pregnancy following her attempt to have two eggs fertilised during the treatment.
