Kendall Jenner: Jonathan Taylor Thomas Who? Only "Old People" Know '90s Teen Heartthrob

Kim Kardashian's 16-year-old kid sister has never heard of Home Improvement star

Kendall Jenner is darling, but…homegirl needs a lesson in '90s teen idols stat.

Kim, Khloé and Kourtney Kardashian's 16-year-old kid sis does not—gasp—know who Jonathan Taylor Thomas is.

A friend of the brunette beauty tweeted that she was "Browsing Tiger Beat w/ @KendallJenner &she doesnt  know who JTT is! JTT FOREVER!"

Said gal-pal even posted a glorious shot of the teen heartthrob (complete with a spray tan and frosted tips). But Kendall, clearly not impressed, retweeted her friend adding, "only old ppl know who he is."

While Jonathan, now 31 years old, has kept a low profile in recent years, his work in Home Improvement and The Lion King gives him teen heartthrob tenure for at least another decade.

So, Kendall, still LYLAS, but we recommend a JTT movie marathon ASAP.
