Kardashian Half Sister Kylie to Front Sears 'Crush Your Style' Campaign

Just how many Kardashian sisters are there? Well, it depends on which last name you want to go with because there's Jenners and there's Kardashians. But that's not what we're talking about. No. We're just letting you know 12-year-old Kylie Jenner will appear in an upcoming series of Sears commercials to promote the retailer's Crush Your Style - The Search for America's Top Style Crush contest. See Kylie explain it here.

And then if you want to switch gears a bit, check out her 14-year-old sister, Kendall, who, following her much older sisters, exposes plenty of cleavage in a photo shoot she did with photographer Nick Saglimbeni.

Does this sort of thing perpetuate the trend of kids growing up too quickly? Debate.
