The two newly observed hidden-bottom mesons Zb(10610) and Zb'(10650) with
quantum numbers J(P) = 1(+) are considered as hadronic molecules composed of
BB(*) and B(*)B(*), respectively. We give predictions for the widths of the
strong two-body decays Zb(+) to Upsilon(nS) + pi(+) and Zb'(+) to Upsilon(nS) +
pi(+) in a phenomenological Lagrangian approach.
