Kylie Jenner flashed quite a big of leg at Justin Bieber's "Believe" world premiere in Los Angeles on Wednesday.

The "Keeping Up With The Kardashians" star wore a floor-length black skirt with a thigh-high slit up the left leg. She wore strappy black sandals and a white crop top to complete the look.

Kylie, 16, has been linked to actor Jaden Smith, 15, since November, and he was also present at the premiere. The pair are reportedly no longer together but are still friends.

She recently told Seventeen Prom magazine: "I don't have a boyfriend, but I do really want that boyfriend prom experience. I would want to go with someone who's not afraid, or doesn't think that he's too cool, to show up at my house with a rose corsage. It would be nice for the guy to come over and be respectful and nice while my mom takes prom pics."
