• Fresh from her tour, Fergie, hanging out with friends at New York hotspot Butter in a black-and-white floral dress. The singer wasn’t the only attraction at the packed club: Jamie-Lynn Sigler, in a red flowy blouse, denim shorts and gold gladiator sandals, hung out with Michelle Trachtenberg. (Sigler’s boyfriend, Scott Sartianoco-owns the club, while Trachtenberg is dating a Butter manager.) The ladies got busy on the dance floor, rocking to songs by Jay-Z (“Money Ain’t A Thing”) and Timbaland (“Give It To Me”). Meanwhile, rapper Lil Jon stood atop the banquette dancing – all with a large entourage in tow.

• A newly 21 Ashley Olsen and a fortysomething woman, enjoying the Japanese cuisine at Nobu Malibu. The duo ate sushi from a long, ceramic plate, topped with an assortment of cut rolls. Also dining together at Nobu: Cheryl Hines and her hubby.

Martha Stewart, buying fresh, made-by-hand mozzarella at East Hampton’s restaurant Tutto Italiano. Stewart also ordered two specialty pizzas during her stop there. She also was spotted dining with two friends at Nick & Toni’s, and the group feasted on zucchini chips, arugula salad, Fedelini pasta with saffron mussels, black grouper, rib eye steak and swordfish.

• Just before production gears back up for NBC’s Heroes,the cast took time to celebrate Missy Peregrym‘s 25th birthday at the Roxy in Los Angeles. With date (and Pittsburgh Steelers quarterback) Ben Roethlisberger by her side, the actress, in a black tank top and Christian Louboutin pumps, told us, “It’s a big deal that everyone made about [my birthday,] . . . I think it’s going to be a lot of fun.” And even young costarNoah Gray-Cabey joined in on the festivities –which featured music by band Another Big Machine.

• The cast of the upcoming film HairsprayQueen Latifah, Zac Efron, Amanda Bynes and others – conversing in a sing-song manner over a meal at West Hollywood’s Koi. (Hey, they did just film a musical!) According to an onlooker, the group started talking in “high-pitched, musical voices, questioning and answering each other.” The friendly bunch couldn’t stay in tune for too long, though. They kept bursting into laughter, the onlooker tells us.
