The birth of their first baby, Mason Dash Disick, in December 2009 was watched by 4.8 million people in E!’s most-watched telecast ever at the time. The news comes almost a month after Kourtney’s sister Kim announced that she and her husband, Kris Humphries, were getting a divorce after 72 days of marriage.
