Screened modified gravity is inherently elusive: screening mechanisms suppress the propagation of additional gravitational degrees of freedom in typical astrophysical scenarios, allowing these theories to avoid constraints coming from weak field observations. However, only few work has been done to explore the validity of screening mechanisms in dynamical relativistic regimes, such as in the interior of neutron stars. In this talk I will briefly review screened modified gravity models endowed with chameleon screening and discuss recent results regarding chameleon-(un)screened neutron stars.
