Some new physics models, such as "beautiful mirrors" scenario, predict the existence of the bottom partner B'. Considering the constraints from the data for the Z -> b (b) over bar branching ratio R-b and the FB asymmetry A(FB)(b) on the relevant free parameters, we calculate the contributions of B' to the cross section sigma (Zb) and the Z polarization asymmetry A(Z) for Zb production at the LHC. We find that the bottom partner B' can generate significant corrections to sigma (Zb) and A(Z), which might be detected in near future.
