Kourtney and Scott Have Come a Long Way

Although the couple appeared to be adjusting well to their comfortable relationship, trouble popped up again after Penelope was born when a male model claimed that he was the real father of Mason. The model filed a paternity suit and Scott reportedly moved out as a result of the drama. This eventually led to Scott taking a paternity test in August 2013, which proved that he was indeed the father of Mason.
