Kylie Jenner Meets Kylie Jenner's Wax Figure, Confusion Ensues

One of these chicks used to bang Tyga ... the other was probably a scented candle.

Kylie Jenner hit up Madame Tussauds in Hollywood Tuesday for the unveiling of her doppelganger ... and it's absolutely uncanny. Seriously, pop quiz, hot shot -- if they were dressed alike, would you really be able to tell 'em apart?

Even Kylie had some fun with her new BFF on social media.

The real winner here is Tyga. There IS another, and she's a real cheap date!
