Abstract
The goal of the paper is to show that the event horizons of the spacetimes
constructed in \cite{KS}, see also \cite{KS-Schw}, in the proof of the
nonlinear stability of slowly rotating Kerr spacetimes $\mathcal{K}(a_0,m_0)$,
are necessarily smooth null hypersurfaces. Moreover we show that the result
remains true for the entire range of $|a_0|/m_0$ for which stability can be
established.
