Kylie Jenner is often left in tears by some of the vicious social media attacks directed at her by her boyfriend's much older ex-girlfriend, Blac Chyna.

According to HollywoodLife, ever since 17-year-old Jenner and Tyga began seeing each other, it seems the disses and the bullying have never stopped coming Chyna, who is also the mother of Tyga's young son.

"Kylie's trying hard to stay strong and not let it upset her but it's tough," a source said of the "Keeping Up with the Kardashians" reality show star's mood. "She's way more sensitive than she likes to admit. The things Blac and her friends say to her are very hurtful. They make her cry. But she'd never want Blac to know that."

Even when Jenner has tried to take a stance, like blocking Chyna from all her social media platforms, the digs persist.

"She's set up fake accounts so she can still bully Kylie and she has her friends sending nasty messages too," said a source. "Blac acts like she's above this but she's always stirring sh- up."

Things don't figure to let up anytime soon, what with Kylie and Tyga, 25, now rumored to have set a date on which they plan to elope.

"Right now their plan is to get hitched in August," a source recently told Radar, noting that is the same month in which Jenner is set to turn 18. The source added, "They are making plans to quit LA, for a brand new life away from her family and his baby mamma, Blac Chyna."

Among the potential relocation possibilities are rumored to be New York City and even Europe. Recently, Jenner has been spotted sporting a large ring on her left hand, prompting some to speculate that the couple may have already taken a next step in their relationship.
