In this new parody video, “Kristen Stewart” explains why she cheated on Robert Pattinson.

It’s not Kristen, obviously. It’s a look-alike actress named LAURA MCDONALD.

The video features “K-Stew” trying to convince Rob that none of the cheating was her fault.

It’s intercut with scenes of “Snow White” director RUPERT SANDERS tricking Kristen into cheating on her in various ways that just get more and more ridiculous.

Finally, he just tells her he has a condition, which can only be cured through sex with Kristen Stewart.
