• Ashley Olsen and boyfriend Justin Bartha, double-dating with another couple at L.A.'s Sunset Tower Hotel's Tower Bar. The foursome took a table in the middle of the restaurant, but that certainly didn’t deter Olsen from cozying up to her beau. The two sat next to each other, often holding hands and making plenty of eye contact. Over dinner, the petite starlet – who appeared to be in a great mood – sipped a martini and even fed Bartha bites of her organic roast chicken.

• Hayden Panettiere, causing a stir on Canon Drive in Beverly Hills as she left the Thibiant Spa. After a facial, the Heroes star was greeted by more than 30 photographers who had camped outside. Panettiere had to struggle to pass through the blinding crowd and slide into the driver's seat of her maroon Porsche Cayenne. Even after she started to pull away, the paparazzi flashed their bulbs through the windshield.

• Tyra Banks, dressed casually in jeans, boots, no makeup and her usual ombre Prada purse, waiting patiently in line for her sugar fix at Magnolia Bakery on New York's Upper West Side. After paying, she and a female friend grabbed seats at one of the bakery's communal tables and tucked in to their desserts out of paper boxes.

• Ashton Kutcher, in a white golf tee and black sweats, watching the homecoming game from the sidelines at L.A.'s Harvard-Westlake High School. The actor, who is an assistant coach for the school's freshman team, chatted with coaches as a gaggle of high school girls sat in the stands, giggling like, well, schoolgirls at the "amazingly cute" actor. Earlier, Kutcher waved to his female fans by the locker room, and they dissolved into a fit of giggles.

• Following his triumphant SNL hosting gig, Josh Brolin headed to the show's afterparty at New York's Wildwood Barbeque with wife Diane Lane. "[They] were really cute," says an observer. "Josh was talking to everybody." For her part, Lane sipped tea at a back table, and stayed away from the action, while SNL castmembers Andy Samberg and Seth Meyers yukked it up one table over. No sign of guest star (and Republican VP nominee) Sarah Palin, though. According to a source, the politician planned to go, but pulled out of the bash at the last minute.

• Juliette Lewis, running into the T-Mobile G1 launch party at Skylight in N.Y.C. to see Jack White and his band The Raconteurs.

• By KRISTIN BOEHM, JENNIFER GARCIA, MAUREEN HARRINGTON and LESLEY MESSER
