Kylie Jenner has grown more "introverted" as she's gotten more famous.
The 'Keeping Up With the Kardashians' star used to keep friends and family entertained with her "crazy" antics, but these days she finds it difficult just making small talk with people.
She said: "I'm not a shy person and when I was younger I was so crazy.
"Every time my mum would have people over, I'd make everyone come in and watch me do my dance moves.
"It was so wild. And I feel like growing up in the spotlight, it just made me a more introverted person. Now I can't walk in a room and talk to people."
"It's weird. I'm super-reserved and introverted but I know everyone knows who I am."
And the 18-year-old beauty - who has an on/off relationship with rapper Tyga - admits she feels a lot of pressure to always be in a good mood when she's out in public.
She explained to Elle magazine: "I don't know if people like me but they have an idea of me and it's a lot of pressure to go up to someone and be like, 'Hey, what's up?'
"Or if you act even a little tired that day, people think you're a bitch. It's just... I don't know. I just keep it to myself."
