The reality star opens up about her struggles with stardom – and many other topics – in her cover story for Elle UK's February issue.
Bieber, who according to multiple sources has been hooking up with Jenner's older sister Kourtney Kardashian, knows a thing or two about dealing with fame since becoming a teen sensation at a young age.
"I'm so close to him because I feel like he's been through exactly what I've been through in a completely different way but very similar," Kylie, 18, tells the publication.
"He gets me, and every time I see him he always sits me down and is like, 'Are you OK? You're amazing. You can get through this, just stay true to yourself.' He helps me a lot."
The 21-year-old singer has become very close to the Kardashian-Jenner family. Bieber has been good friends with not only Kylie, but also her older sister Kendall Jenner. Momager Kris Jenner is also a fan of the Canadian pop star as is her boyfriend Corey Gamble, who works as Bieber's road manager.

Another person near and dear to Kylie is parent Caitlyn Jenner. "Everything's out in the open and now we're closer," the she, adding, "I feel like we want to hang out more. I think there was always something on her mind before she transitioned."
While Justin and Caitlyn help Jenner deal with fame, she admits her days of Instagram and Snapchat aren't forever. In fact, if Jenner becomes a mother, social media may be out of her life for good.
"Once I have a kid I'm not going to be on Instagram," she says. "You know, I'll probably delete my Instagram and just … I don't know, live life."
