The reality star, who also has a two-year-old daughter, North, gave birth after suffering a difficult pregnancy.
Kanye’s wife was due close to Christmas Day, but it’s thought she brought her date forward to avoid complications.
The announcement which was on Kim’s official app read: “Kim Kardashian West and her husband, Kanye West, welcomed the arrival of their son this morning. Mother and son are doing well.”
