ICE SCREAM: Kate Spade held her biannual breakfast Monday to show her spring collection. Perhaps in an ode to the ongoing heat or just the California à la Gidget theme, the designer feted guests with frozen treats along with the usual fare. Parked outside the showroom was the Kate Spade Ice Cream Soup "truck" complete with piano-playing pitchman. The truck — which was featured in a documentary film titled "Ice Scream Soup" shot by Andy Spade — was commissioned from artist Josh Sesbiu and has been making the rounds around fashion week. Perhaps the next film will feature daughter Francis B., two-and-a-half, who was being trailed by Casey Neistat, a filmmaker, for the day.
