Kendall Jenner continues to prove that she is all grown up. This time she does it by posing topless for the June/July issue of Interview magazine.

The 18-year-old reality TV star talked about -- ironically enough -- her childhood.

"When I was little, I would always lie about the stupidest things," she told the magazine. "In kindergarten or first grade, I would tell people I had tigers living in my attic and a room full of gold. I would tell people I was from Hawaii, but I had a Southern accent. I was the biggest liar for no reason, and then as I got older, I thought, 'Why am I lying to everybody?'"

Now she only lies to her younger sister about stealing her clothes.

At such a young age, Jenner is already doing what she wants. Growing up, she always looked up to supermodels and considered them her "superheroes."

But, she was also inspired by her father.

"My dad is my everything," she said. "He always had the craziest speeches for Kylie [Kendall's younger sister] and me growing up, good words to live by."

His best piece of advice?

"'Dream big, work hard.' My parents brought up Kylie and me to be workaholics. That's something I really appreciate."

And she surely made her father, Olympian athlete Bruce Jenner, proud when she set the record for the high jump at her high school.

She recently moved into her own apartment, which is described as a more than $1 million high-rise condo in Los Angeles. On "Live! With Kelly and Michael," she said that her mother, Kris Jenner, "cried herself to sleep a couple of nights" when she first moved out.
