Kanye West isn't happy with Scott Disick. 

The 38-year-old rapper is reportedly upset with the "Keeping Up with the Kardashians" star for betraying and abandoning his sister-in-law Kourtney Kardashian and their three children 5-year-old Mason, 3-year-old Penelope and 6-month-old Reign.

Disick and Kourtney ended their 10-year relationship after photos surfaced of the rumored party boy getting super cozy with his ex-girlfriend Chloe Bartoli in the South of France, Us Weekly reported.

A source told PEOPLE that Kim Kardashian's husband is questioning Disick's role as a boyfriend and father, but his main concern is for his nieces and nephews.

If Disick continues to abandon his responsibilities, West is willing to help his sis-in-law provide for her children and be a positive role model for them. The rapper was reportedly spotted taking his nephew Mason to the cinema last week.

"Kanye is furious, maybe the most furious of everyone. He's saying that a real man doesn't abandon his family like Scott is doing," a source close to the rapper told PEOPLE. "He has made it crystal clear that he's willing to step in and be a strong male figure to the kids if they need him to be. He feels strongly about that."

A source previously told people that the mother-of-three called it quits with her longtime boyfriend for the sake of their children. The source said that the Kardashian clan would consider giving Disick a second chance if he was committed to fixing his life.

"If Scott comes back and faces things like a grown man, he'll be surprised how much forgiveness there can be - from every member of the family. He needs to have a healthy relationship with his kids, and he can't have that unless he has a healthy relationship with Kourtney and her family. Everyone's hoping he finally makes the right choice," the source added.
