  Inflationary and hence quantum origin of primordial perturbations is on a
firmer ground than ever post the BICEP2 observations of primordial
gravitational waves. One crucial ingredient of success of this paradigm rests
on explaining the observed classicality of cosmological inhomogeinities despite
their quantum origin. Although decoherence provides a partial understanding of
this issue, the question of single outcome motivates the analysis of quantum
collapse models in cosmological context which generically modify the dynamics
of primordial perturbations and hence can leave their imprints on observables.
We revisit one such recently proposed working model of classicalization by
spontaneous collapse \cite{Das:2013qwa} in the light of BICEP2 observations to
look for possible modifications to tensor power spectra and their implications.
We show that it can potentially change the consistency relation of single-field
models and a precise measurement of $n_T$ and its running could serve as a test
of such dynamics in the early universe.
