Paris Jackson Is 'Scared' for Justin Bieber, and 12 Other Things We Learned From Her 'Rolling Stone' Tell-All

Paris Jackson is getting candid in her first-ever in-depth interview.

The 18-year-old daughter of the late Michael Jackson appears on the latest cover of Rolling Stone magazine, where she opens up about her father's tragic death, past struggles with depression and drug abuse and attempting suicide.

Now, ET's rounded up 13 things we learned from the tell-all feature, appropriately titled Paris Jackson: Life After Neverland.

1. She's "scared" for Justin Bieber.

The platinum blond beauty recalls feeling terrified for the pop star after seeing him perform during a recent tour, claiming Justin appeared exhausted. "He was tired, going through the motions," she claims, which reminded her of "how my dad was exhausted all the time but couldn't sleep" during his This Is It comeback tour.

"I'd tell [my dad], 'Let's take a nap,'" she remembers. "Because he looked tired. We'd be in school, meaning downstairs in the living room, and we'd see dust falling from the ceiling and hear stomping sounds because he was rehearsing upstairs."

ET reached out to a rep for the "Sorry" singer on Tuesday, who had no comment regarding Paris' opinions.

2. She was sexually assaulted by a "complete stranger" at age 14.

"I don't wanna give too many details," she exclaims. "But it was not a good experience at all, and it was really hard for me, and, at the time, I didn't tell anybody."

3. Rolling Stone claims Paris says she attempted suicide more than once.

Back in June 2013, when Paris was only 15 years old, she made headlines for attempting suicide by cutting her wrists and taking 20 Motrin pills, which her mom, Debbie Rowe, later confirmed to ET. At the time, Debbie told ET that Paris had "a lot going on [lately]," with a source claiming to ET that the reason for the attempt was because she wasn't allowed to go to a Marilyn Manson concert scheduled on the sixth of that month at Los Angeles' Gibson Amphitheater, which also featured her "bae," Alice Cooper.

"It was just once that [a suicide attempt] became public," Paris explains to Rolling Stone, revealing she had been cutting herself and hiding it from her family in 2013. "It was just self-hatred, low self-esteem, thinking that I couldn't do anything right, not thinking I was worthy of living anymore."

Of course, June will always be a tough month for Paris -- her father died on June 25, 2009, at age 50.

4. Her depression and drug use was a result of not fitting in.

Although better and sober today -- "I'm a completely different person!" -- Paris admits she once struggled with depression and drug abuse, which she says first started when she entered a private school in the seventh grade. She recalls not fitting in with kids her own age at all, resulting in her hanging out "with a lot of older people doing a lot of crazy things."

"I was doing a lot of things that 13-, 14-, 15-year-olds shouldn't do," she explains, telling the magazine her dad also suffered from the disease and the two were actually prescribed the same antidepressants. "I tried to grow up too fast, and I wasn't really that nice of a person."

5. Some of her tattoos are actually cover-ups for track marks she obtained from using drugs.

"I was crazy. I was actually crazy," Paris, who has acquired more than 50 tattoos, nine of which are dedicated to Michael, confesses. "I was going through a lot of, like, teen angst. And I was also dealing with my depression and my anxiety without any help."

6. Modeling has helped boost her confidence

The edgy teen made her debut at Paris Fashion Week just last week, attending the Givenchy Menswear Fall/Winter 2017-2018 runway show. "Plenty of people think I'm ugly, and plenty of people don't," she says. "But there's a moment when I'm modeling where I forget about my self-esteem issues and focus on what the photographer's telling me -- and I feel pretty. And in that sense, it's selfish."

She also claims that the late King of Pop advised her to go after her dreams, once telling her, "If you wanna be bigger than me, you can. If you don't want to be at all, you can. But I just want you to be happy."

7. Paris believes Michael is her biological father, despite all those speculation theories claiming he is not.

"He is my father," Paris stresses. "He will always be my father. He never wasn't, and he never will not be. People that knew him really well say they see him in me, that it's almost scary."

"I consider myself black," she adds. "[My father] would look me in the eyes and he'd point his finger at me and he'd be like, 'You're black. Be proud of your roots.' And I'd be like, 'OK, he's my dad, why would he lie to me?' So I just believe what he told me. 'Cause, to my knowledge, he's never lied to me."

She says that most people who don't know her, however, "call me white."

"I've got light skin and, especially since I've had my hair blond, I look like I was born in Finland or something," she jokes.

8. She believes her father was murdered, and seeks proper justice.

Dr. Conrad Murray served two years in jail for the involuntary manslaughter of Michael after he died following a powerful dose of the anesthetic propofol. Paris still harbors suspicion, and believes her father was, in fact, "absolutely" murdered.

"Because it's obvious," she alleges. "All arrows point to that. It sounds like a total conspiracy theory and it sounds like bulls**t, but all real fans and everybody in the family knows it. It was a setup. It was bulls**t."

"He would drop hints about people being out to get him," she continues. "And at some point he was like, 'They're gonna kill me one day.'"

"I definitely [want justice]," she adds, "but it's a chess game, and I am trying to play the chess game the right way. And that's all I can say about that right now."

9. Growing up, she and her siblings (Prince, now 19, and Blanket, now 14) didn't realize their father was a legend.

"I just thought his name was Dad, Daddy," Paris, who admits she was "a really weird kid," dishes. "We didn't really know who he was. But he was our world. And we were his world."

And aside from spending time in Neverland -- their father's Santa Barbara, California, estate, which was equipped with an amusement park, zoo and movie theater -- Paris claims "we actually had a pretty normal life."

"We had school every single day, and we had to be good," she recalls. "And if we were good, every other weekend or so, we could choose whether we were going to go to the movie theater or see the animals [in Neverland] or whatever. But if you were on bad behavior, then you wouldn't get to go do all those things. ... We couldn't just go on the rides whenever we wanted to."

According to Paris, she and her siblings were given the option to go to regular school, but declined. "We were like, 'We don't need friends,'" she explains. "We've got [dad] and Disney Channel!"

10. She remembers times when her father would get emotional in front of her.

"My dad would cry to me at night," she confesses, touching on the multiple child-molestation allegations against the "Man in the Mirror" singer. "Picture your parent crying to you about the world hating him for something he didn't do. And for me, he was the only thing that mattered. To see my entire world in pain, I started to hate the world because of what they were doing to him. I'm like, 'How can people be so mean?'"

"Nobody but my brothers and I experienced him reading A Light in the Attic to us at night before we went to bed," she adds. "Nobody experienced him being a father to them. And if they did, the entire perception of him would be completely and forever changed."

11. She says Michael may be gone, but still visits her in her dreams.

"I feel him with me all the time," she says, admitting that she's still not over his tragic death. "They always say, 'Time heals,' but it really doesn't. You just get used to it."

"I live life with the mentality of 'OK, I lost the only thing that has ever been important to me,'" she continues. "So, going forward, anything bad that happens can't be nearly as bad as what happened before. So I can handle it."

12. Paris says Michael prepared her and her siblings for the real world.

"He did not bulls**t us," she recalls. "You try to give kids the best childhood possible. But you also have to prepare them for the s***ty world."

13. She finds visits to the Museum of Death in Hollywood, California, miraculously soothing.

As morbid as it sounds, Paris admits she's "desensitized" to graphic reminders of human mortality. "It's awesome," she says of her ninth visit to the museum, which features serial killer memorabilia, decapitation photos and pics from the morgue of the world's most famous crime scenes. "They have a real electric chair and a real head!"
