We have explored cold dark matter and holographic dark energy cosmologicalmodels with big rip singularity. To obtain the solution of the field equation,we have supposed that scalar expansion $\theta$ is proportional to shear scalar$\sigma ^2 $ which leads to $p_1=(p_2) ^n $, where $A_1 $, $A_2$ are metricpotentials and $ n$ is constant. Big bang and Big rip singularity areinvestigated and analyzed the state-finder parameter. The physical andgeometrical parameters of the universe are explained.
