It is demonstrated that if cosmic dark energy behaves like a fluid with equation of state p = \rm w ρ(p and ρ being pressure and energy density respectively) as well as generalized Chaplygin gas simultaneously, Big Rip or Big smash problem does not arise even for equation of state parameter \rm w < -1.Unlike other phantom models, here, scale factor for the future universe is found regular for all time.
