The 14-year-old reality TV star - who is rumoured to be dating Jaden Smith - loves Robert's character Edward Cullen from 'The Twilight Saga' and wishes the vampire was a real person.
She told Life and Style magazine: "My celeb crush is Robert Pattinson. I probably love his 'Twilight' character and not really Rob though."
While she fancies Robert, Kylie's older sister, Khloe Kardashian, says she's smitten with Jaden, 14, because he is so "sweet" but refused to confirm if they are dating.
She recently said: "I'm kind of obsessed with Jaden. I think he's so sweet. But I will also say they're teenagers and I really can't keep teenagers straight. You just never know. Everything is up and down, but they're definitely best friends, I can tell you that.
"I love Jaden. I cannot keep track of teenage love and I wouldn't expect anyone to keep track of my teenage love when I was a teenager. Why don't you ask Kylie."
