A recently proposed variation on the usual procedure to perform the topological B-twist in rigid N=2 models is applied to the case of the σ model on a Kähler manifold. This leads to an alternative description of Witten's topological σ model, which allows for a proper BRST interpretation and ghost number assignement. We also show that the auxiliary fields, which are responsible for the off shell closure of the N=2 algebra, play an important role in our construction.
