Another week, another unannounced party visit? Will Smith surprised organizers at an exhibit put on by Five Four Clothing and Cyrcle, an L.A.-based art group. “His visit was so unexpected,” a source says. “He just walked around eating ice cream sandwiches and taking pictures.” The actor, who arrived with a female friend, was in a “joking mood,” the source says, and even teased one of the designers about their work. He also tried to buy one of the pieces, but it had already been sold, so Smith made plans to visit Cyrcle’s studios and commission a work.
