Kylie Jenner says her sister Kourtney Kardashian helped her to lose 15 pounds while the two reality stars are facing major issues in their lives right now, Us Weekly reports.

"My sister Kourtney had her third baby recently, and she is on a workout kick to get her body back. She lives up the street, so I'll join her for a trainer session sometimes," Jenner revealed.

"I also started going to this nutritionist because I was having a bad reaction to dairy. I feel like it made me gain a lot of weight. I've now cut out dairy, and it's helping me get back in shape."

Jenner has also credited Justin's Almond Butter packets to her weight loss since she snacks on them whenever she gets hungry during the day.

Kardashian is facing a big break up between her and Scott Disick at the moment while they have three children together. At the same time, Jenner is facing anxiety attacks for being bullied so much and living her life under constant spotlight, according to Business Standard.

"People are so quick to say horrible things about me every day over and over and sometimes I can't take it. Even I at times get affected by it, I breakdown, I hide, I cry," she revealed.

The 18-year-old reality TV star is also running into issues with her boyfriend's ex-girlfriend and baby mother. Blac Chyna allegedly told Jenner to "get a prenup" amidst rumors that she and Tyga are going to tie the knot.

Reports have also said that Jenner pays Tyga's rent and that she has to make payments on a Lamborghini that he bought her for her birthday.

Meanwhile, Kardashian is facing rumors that she cheated on Scott Disick and that her last son Reign is not biologically his. This isn't the first time she has been accused of cheating and letting another man father her children.
