Kendall Jenner -- I Can Do Porn

We're not saying she's going to, but Kendall Jenner can totally do porn now if she wants -- because today marks the reality star's 18th birthday.

Which brings us to our list of other awesome things she can do now that she's 100% legal:

1) Buy cigarettes
2) Vote
3) Strip
4) Get a tattoo
5) Enlist in the military
6) Buy a gun
7) Get tried as an adult

Unfortunately, the one thing she still can't do is drink alcohol ... at least in the U.S. of A.
