Ed Westwick was partying with a guy friend at Trousdale in L.A., but the Gossip Girl star's attention was focused on female clubgoers – and they were most definitely watching him, too! At one point, the British actor invited a group of ladies to sit down and join him, and when they did, he ordered a round of shots. According to an onlooker, Westwick was charming, making the female clubgoers blush as she showered them with his attention – and drinks.

• Meanwhile, his Gossip Girl costar Leighton Meester enjoyed some downtime at the Tides Zihuatanejo resort in Mexico, where the actress and her pals relaxed in a private suite that had an outdoor patio and pool. The group occasionally ventured out to the beach and also checked out a barbeque at night.

Robert Downey Jr., having a belated birthday celebration with wife Susan Downey and three friends at Fig & Olive Melrose Place in L.A. The actor, who recently turned 46, was in a jovial mood and was dressed for the occasion in a pink suit and white shirt. The group shared dishes like crostini, an endive beet salad and some rosemary lamb chops.

Brooklyn Decker got a personalized birthday treat from Crumbs Bakery: vanilla cupcakes topped with Skittles and vanilla cream cheese frosting. The confections aren't on the menu, and the supermodel enjoyed them at home before catching a flight out of N.Y.C.

Paul McCartney chatted up the staff at the Apple store at West Hollywood's The Grove, asking questions about the merchandise before buying a MacBook Pro. The rocker was sporting mirrored shades and, according to an onlooker, "seemed cheery and eager to learn" about his new computer.
