  We revise the future fate of a group of scalar-tensor theories known as
kinetic gravity braiding models. As it is well-known, these theories can safely
drive the expansion of the universe towards a future de Sitter state if the
corresponding Lagrangian is invariant under constant shifts in the scalar
field. However, this is not the only possible future state of these
shift-symmetric models as we show in this letter. In fact, future cosmic
singularities characterized by a divergence of the energy density can also
appear in this framework. We present an explicit example where a big rip
singularity is the only possible future fate of the cosmos.
