We formulate a light-front spectator model for the proton incorporating the gluonic degree of freedom. We investigate the helicity distribution which is consistent with existing experimental data and satisfies the perturbative QCD constraints at small and large longitudinal momentum of gluon in this model. We present the transverse momentum dependent distributions (TMDs) for gluon in this model. In terms of GPDs at non-zero skewness, we also investigate the entire three-dimensional representation of gluons. We address the total angular momentum contribution of the gluons by using the Ji's sum rules and also give our predictions for the kinetic orbital angular momentum in the light-cone gauge.
