A new approximate metric representing the spacetime of a rotating deformedbody is obtained by perturbing the Kerr metric to include til the second orderof the quadrupole moment. It has a simple form, because is Kerr-like. ItsTaylor expansion form coincides with second order quadrupole metrics with slowrotation already found. Moreover, it can be transformed to an improvedHartle-Thorne metric, this guarantees its validity to be useful in studyingcompact object, and that it is possible to find an inner solution
