Kylie Jenner looks tired as she arrives back in LA after celebrating her 18th birthday in Mexico

Kylie Jenner looked like she was feeling the effects of her 18th birthday party celebrations. Wearing the Klan trademark of over-sized sunglasses she made her way through her natural habitat - LAX Airport. But Kylizzle, 18, went for over-over-sized shades that covered up the best part of her face. Got heavy eyes Kylie?
