The photoionization of helium ion in bichromatic circularly polarized XUV laser pulses is investigated by solving the time-dependent Schrodinger equation. It shows that the electron can reach the continuum at the same momentum by absorbing one high-energetic photon or two low-energetic photons sequentially, and these two pathways can interfere with each other. Moreover, the interference can induce the asymmetrical round and the spiral-loop photoelectron momentum distributions in bichromatic circularly laser fields without and with the time delay.
