  We interpret the cosmological constant as the energy of the vacuum, and under
a minimum amount of assumptions, we show that it is deformed in the vicinity of
a black hole. This leads us to reexamine the Kerr-de Sitter solution. We
provide a new solution, simpler and geometrically richer, which shows the
impact of the rotation in form of a warped curvature. We carry out a detailed
and exact study on the new black hole solution, and we conclude with a
conjecture regarding the possible impact of our results on alternative
theories.
