The supermodel attended Jonathan Ross' Halloween bash last night in London with hubby Jamie Hince and daughter Lila Grace.
Kate and Jamie were a matching Day of the Dead couple, complete with skeletal face paint and black unruly locks, while her mini me looked like a brain-starved zombie.
Somehow Mossy still managed to make death look seksi, especially with her dramatically ruffled rose print dress.
