Looks like Bristol Palin’s relationship with Levi Johnston was all just a big political lie.  Levi’s sister Mercede has come out of the cave and spoken with Star Magazine to expose Bristol’s true colors.

Mercede claims that while Bristol and mom Sarah welcomed Levi into their family for the cameras during the election, the family has since shut Levi off from his son Tripp’s life.  Bristol apparently no longer allows Levi to take Tripp to his house because she’s afraid he’ll end up all white trash like his people.

Star reportedly also has some secrets about other Bristol lies, cheating, and some plan that Levi supposedly has to get his kid back.
