We report the discovery of a <CDATA<i long stellar stream in the Milky Way halo, which criss-crosses the well known ?GD-1? stream. We show that this new stellar structure (?Kshir?) and GD-1 lie at similar distance, and are remarkably correlated in kinematics. We propose several explanations for the nature of this new structure and its possible association with GD-1. However, a scenario in which these two streams were accreted onto the Milky Way within the same dark matter sub-halo seems to provide a natural explanation for their phase-space entanglement, and other complexities of this coupled system.
