In this work we calculate the pole-mass of the $\rho^0$ meson with differentspin projections $s_z=0,\pm 1$ in the context of the magnetized two-flavorNambu--Jona--Lasinio model. Making use of the mean field approximation toobtain the effective quark mass as a function of the magnetic field, we applythe random phase approximation (RPA) to the vector channel in order tocalculate the polarization function for each spin component. We adopt themagnetic field independent regularization (MFIR) in our evaluations as a methodof separating divergences and the Pauli-Villars regularization for the vacuumcontributions. The $\rho^0$ meson mass with spin projection $s_z=\pm 1$ isalways catalysed with the magnitude of the magnetic field, showing goodagreement with Lattice QCD results. The mass projection $s_z=0$ has anon-monotonic behavior, decreasing until the minimum at $eB\lesssim 0.15$GeV$^2$, which is in contrast with available LQCD data.
