  Relativistic bipartite entangled quantum states is studied to show that
Nature doesn't favor nonlocality for massive particles in the
ultra-relativistic limit. We found that to an observer (Bob) in a moving frame
S', the entangled Bell state shared by Alice and Bob appears as the
superposition of the Bell bases in the frame S' due to the requirement of the
special relativity. It is shown that the entangled pair satisfies the Bell's
inequality when the boost speed approaches the speed of light, thus providing a
counter example for nonlocality of Einstein-Podolsky-Rosen(EPR) paradox.
