The West family is about to get bigger. Kanye West and Kim Kardashian are expecting their third baby to arrive by the end of January, according to TMZ.

KimYe reportedly hired a surrogate to carry their third child due to Kardashian’s placenta accreta, a medical condition that would have made it dangerous and possibly life-threatening for the reality television star-turned-mogul to give birth a third time.

According to the report, the surrogate was hired for $45,000 and is prohibited from activities that may endanger the baby, including smoking, drinking alcohol, using drugs, or getting into hot tubs. Dietary restrictions are also in place.

Last month, after initial rumors of the surrogate circulated, Kardashian discussed having a third child with The Hollywood Reporter. “I hope so,” she said. “There have been a lot of things said and Kanye and I have not confirmed anything. We’re definitely trying. We are hoping so.”

Kim and Kanye have not made a public announcement about the baby’s forthcoming arrival as of yet. The famous power couple — who recently launched a kids’ clothing line — already have a four-year-old daughter, North West, and a one-year-old son, Saint.

Congratulations to the Wests!

UPDATE: Sources familiar with the pregnancy tell TMZ that Kim and Kanye’s surrogate is carrying a baby girl. This will be the ninth girl in the Kardashian family, not including Kris Jenner.
