Kanye West has a "problem controlling his impulses".
The 'Love Lockdown' hitmaker has been behind a number of foul-mouthed rants over the past few weeks but a source insists his outbursts have no effect on his family life with wife Kim Kardashian West and his two children, North, two and Saint, two months.
A source told PEOPLE magazine: "It's been a rough week for Kim. She has lots of support from her family though. Everyone knows that Kanye, once in a while, goes on public rants and they are all very understanding that it's exhausting for Kim. It's like a tick that he has.
"When he starts his rants, it's very difficult for him to stop. When he starts venting, it's like he needs to get it all out. Kanye might seem mentally unstable at times, but there has never been any concern for Kim, or the kids. Kanye just has a problem controlling his impulses. It's not anything that usually affects their everyday life. Their marriage is not perfect, but there are no plans to split."
But despite Kim assuring her family everything is alright, mother Kris Jenner is reportedly still worried he could "damage" the Kardashian brand.
An insider said previously: "His Twitter rants are out of control, and Kris fears that he's taking the family down. Kris wants Kanye to hire someone to handle all the noise and drama so he can focus on being an artist."
