  We prove the local Lipschitz regularity of the local minimizers of scalar
integral functionals of the form \begin{equation*} \mathcal{F}(v;\Omega)=
\int_{\Omega} f (x, Dv) dx \end{equation*} under $(p,q)$-growth conditions. The
main novelty is that, beside a suitable regularity assumption on the partial
map $x\mapsto f(x,\xi)$, we do not assume any special structure for the energy
density as a function of the $\xi$-variable.
