In today's reminders that we are aging, here is a gem from a teen model whose been living under a rock, Kendall Jenner. The 17-year-old model and reality TV star and lil sis to Kim K was recently looking at old issues of Tiger Beat (do you remember Tiger Beat??) and was dumbfounded by this now old hunk."only old ppl know who he is," chirped Kendall.

For the record, JTT is now 31 years old. Kendall's sister Kim Kardashian is 32. Just throwin' that out there. So, what are you saying Kendall? That 31 is the new 71? Kendall!!! way to grow your fan base!

When JTT was big all of my former girlfriends had his poster up. Any Fun 107 listeners have a JTT poster on their bedroom wall back when you were Kendall's age? Anybody?
