Kim Kardashian and Kanye West expecting a boy

The latest Kardashian to keep up with is on the way, Kim Kardashian said, confirming rumors that she and rapper Kanye West are expecting a fourth child via surrogate.

The lifestyle mogul and reality TV superstar told the US program "Watch What Happens Live With Andy Cohen" late Monday that her family´s newest addition was a boy, and was due "sometime soon."

"It´s out there," she said, sitting alongside sisters Kourtney and Khloe. "I got drunk at our Christmas Eve party, and I told some people, but I can´t remember who I told."

The new baby joins daughter Chicago, who was born last January via surrogate, daughter North, five, and their first son, three-year-old Saint.

Kardashian has been open about her struggles with pregnancy and decision to use a surrogate, as she had previously suffered from placenta accreta — a serious condition where the placenta becomes too deeply attached to the wall of the uterus.
