According to the site, Kourtney, who shares children Mason, seven, Penelope, five, and two-year-old Reign with her long term ex, isn't bothered about his relationship with 19-year-old Sofia 'because she thinks it's genuine and feels good that he's moving on'.

Meanwhile Kourtney is also dating someone younger as well- model Younes Bendjima, 24, who she has been linked with throughout the summer.

Coincidentally, Younes and Sofia used to be friends, but sources report the two have stopped talking since he embarked on a relationship with Kourtney.
