As an addendum to our previous evaluation of the weak-interaction corrections to hadronic top-quark pair production [W. Bernreuther, M. F"ucker, and Z. G. Si, Phys. Rev. D 74, 113005 (2006).], we determine the leading weak-interaction contributions due to the subprocesses bb\ensuremath→tt and gq(q)\ensuremath→ttq(q). For several distributions in tt production at the CERN LHC, we find that these contributions are non-negligible as compared to the weak corrections from the other partonic subprocesses.
