Kylie Jenner "100 per cent" believes in aliens.

The 17-year-old reality TV star says she has no doubt there is life on other planets and admits she is obsessed with space.

She told US Cosmopolitan magazine: "I've been to Area 51 and talked to people who claim to have been abducted. I'm super interested in aliens, but they terrify me because I 100 per cent believe in them."

The 'Keeping Up with the Kardashians' beauty says she was raised to confront her fears by her father, Bruce Jenner.

She said: "He always says to expand your envelope and do things you're afraid of. So I'm always trying to find new things that I'm scared of."

Meanwhile, Jenner, who is rumoured to be dating rapper Tyga, would love to take singing lessons in the future, but insists she isn't planning to launch a career as a pop star in the near future.

She said: "That's a rumour. It would be fun to take singing lessons. But if I ever started it, it would be for fun, then I'd see if it went anywhere.

"My sisters and my mom are super workaholics. Seeing all their success is a big motivation."
