In January, Kardashian admitted that it hasn’t always been easy keeping things peaceful with the father of her children.

“I had to learn to take control of my feelings,” she explained to tmrw magazine at the time.

“There were so many times that my feelings got control of me and I was impulsive and I tweeted something or posted something and things that you regret,” she added.
