Kylie Jenner has been breaking down into tears behind closed doors, weighed down by her parents’ divorce, Bruce Jenner’s transition into Caitlyn Jenner, and the rumors surrounding her 25-year-old boyfriend Tyga. According to a report by Hollywood Life, Kylie has been dealing with “all the drama in her life” once the cameras are off, a source revealed.

“Kylie is a real cool customer in public. She is a lot like her mom (Kris) in that it seems as though nothing phases her at all,” the source told Hollywood Life, adding: “She’s very good at putting herself together and projecting an image of total confidence. She makes it seems like she’s the happiest person in the world.”

The source reportedly also said: “The truth is that when the cameras are off and she isn’t posting playful Snapchats, Kylie is struggling with all the drama in her life,” adding: “She has been through more in her young life than most 17-year-old girls and it can really get to her.”

The report added that at times Kylie breaks down into tears and is unable to stop. “Kylie battles bouts of uncontrollable crying and sadness. She was always dependent on Bruce but now everything has changed. She’s so happy and supportive for Caitlyn, but its incredibly difficult.”

Kylie’s boyfriend Tyga was recently criticized after he allegedly sent a picture of his private parts in a message to transgender model Mia Isabella, with whom he was said to be having a three-year long affair. The source told Hollywood Life that these issues have become stressful for Kylie to handle, especially since people have started bringing them up the Internet.

“Her relationship with Tyga has been really stressful too,” the source said, according to Hollywood Life, adding: “And now she’s getting an onslaught of Internet trolls hating on her because of the accusations that he’s been cheating on her with a transgender woman.”

Tyga, who has a son named King Cairo with Blac Chyna, has denied the allegations of cheating on Kylie, who has reportedly decided to stand by him. However, a recent article said that Caitlyn Jenner is worried that Tyga is manipulating her daughter.

“Caitlyn’s is becoming quite concerned with Tyga and Kylie’s relationship at this point,” the source reportedly said, adding: “Her biggest fear is that Tyga could possibly manipulate her young 17-year-old daughter into doing whatever it is he wants her to do. Cait feels this young man has oil on his tongue and is one slick talker. She’s even witnessed his charm in action many times before but didn’t really think too too much about it until now.”

Meanwhile, rumors are also swirling around claiming that Tyga wants to propose to Kylie and win over Caitlyn's trust.
