Kanye West thinks Kourtney Kardashian's beau is 'toxic'

American rapper Kanye West is reportedly worried about his sister-in-law Kourtney Kardashian, as he thinks Scott Disick is "toxic" for her.

The rapper, who is married to reality star Kim Kardashian, has allegedly gone from loving Disick to thinking that he's "a hot, toxic, mess", who is partying it up "like the world is going to end" while Kourtney is heavily pregnant with their third child, the Mirror reported.

According to sources, West would never leave his wife Kim when she was pregnant, unless it was to bring money back home to the family. Sources added that the rapper can't seem to understand why Disick would want to leave Kourtney while she is pregnant at home with their two children.
