  We find the explicit form of two-point function for the conformal spin-2
energy momentum operators on the near horizon of a near extremal Kerr black
hole by variation of a proper boundary action. In this regard, we consider an
appropriate boundary action for the gravitational perturbation of the Kerr
black hole. We show that the variation of the boundary action with respect to
the boundary fields yields the two-point function for the energy momentum
tensor of a conformal field theory. We find agreement between the two-point
function and the correlators of the dual conformal field theory to the Kerr
black hole.
