Annie Murphy has broken her silence after her former Schitt's Creek TV mother, Catherine O'Hara, died at the age of 71. "Ha-ha-HAAAA?!?! Her laugh was a perpetual 'Yes, And' challenged anyone who heard it to join in, and be as delighted as she was," Murphy, 39, wrote via Instagram on Saturday, January 31. "Gosh, were we ever lucky to have her." Us Weekly confirmed on Friday, January 30, that O'Hara died after a brief illness.
