  We find an exact solution of Kerr-Newman-de Sitter type on the braneworld(4D)
of the DGP model. When a constant 4D Ricci scalar is assumed, only zero(flat)
and a positive(de-Sitter) values satisfy the Hamiltonian constraint equation
coming from the extra dimension. With a Z_2-symmetry across the brane and a
stationary and axisymmetric metric ansatz on the brane, we solve the constraint
equation exactly in the Kerr-Schild form with de-Sitter background. In the
de-Sitter background this Kerr-Schild solution is well behaved under
Boyer-Lindquist transformation: the constraint equation is preserved under the
transformation and so is the solution. In the non-rotating limit we show that
this Kerr-Newman-de Sitter solution has the characteristic of accelerated
expansion of the braneworld universe.
