In a new promo for the upcoming season 19 premiere of ‘Keeping Up With the Kardashians,’ Kim Kardashian confronts her big sister, Kourtney Kardashian, after Scott Disick allegedly talked about possibly ‘going for baby number four.’ The exes share three children together: Mason, Penelope and Reign. The couple split in 2015 after almost a decade of dating and in May, Scott split from Sofia Richie, whom he dated for three years.
