"Off to an intense workout. Can't seem to shake this last 15-20 lbs of baby weight. No more excuses. My baby is 1 years old! UGH (sic)," Kim said in a Twitter post last August 5.

Meanwhile, a tipster from Britain's Grazia Daily said that Kanye can be controlling of Kim and wants her to become the perfect wife, "In the old days, you'd always see Kim smiling when she was having her photo taken. But now, more often than not, she'll be stony-faced," the source said.

On the most recent episode, Kris Jenner had to handle her estranged husband's anger when Bruce Jenner caught her smoking marijuana. Not only was Bruce was upset in the scene, he was also surprised that Kris was smoking with her mother, MJ Shannon.

"As usual, he's not happy with us, because we're having way too much fun," Kris explained.
