Kyra Sedgwick, picking up the first shoes she tried on – a pair of purple Alejandro Ingelmo heels – at Il Primo Passo in Santa Monica. "She was shopping alone and was looking for a pair of shoes to go with a Peter Som dress she was going to buy from Aura boutique," a fellow shopper tells us. "She was very nice and looked great. She was wearing jeans and a ruffled navy top."

Adam Sandler, Kevin James and David Spade, dining together at Stack steakhouse in Las Vegas. Upon arriving, Sandler took off his shirt at the hostess stand and jokingly asked if the restaurant had a dress code. The hostess replied, "Sometimes."
