Very little about Kim Kardashian is real.
Her televised fights are scripted, her engagement was filmed by a camera crew, her Tweets and Facebook posts are paid for by sponsors.
But it's safe to assume Kris Humphries would not have purchased a fake ring for his fiance... right? That's what Jay Leno wanted to find out last night, as he actually set Kim's 20.5 carat rock on fire as a test. (Real diamonds don't burn; a cubic zirconia will catch flame.)
What happened? Did Kim make you believe she wasn't in on this stunt? Watch the video below.
