• Mandy Moore, shopping for home furnishings in Los Angeles.

• Heath Ledger, following a Cinema Society screening of his Bob Dylan-themed movie I'm Not There with a party at the Bowery Hotel in downtown New York. The actor was joined by director Todd Haynesand costar Julianne Moore – who held court on wicker couches. Guests at the bash dined on strip steak and Caprese salads. And the soundtrack to the party came, appropriately, from Dylan's catalogue, with tunes like "Rainy Day Women #12 & 35." Ledger, meanwhile, stayed at the party until the very end.

• Katharine McPhee, enjoying a turkey sandwich and an Orangina on the patio of Belwood Bakery in Studio City, Calif. Without makeup, the former American Idol runner-up still looked gorgeous in skinny jeans and flip-flops. The singer was also in a great mood, an onlooker says, as she chatted it up with a girlfriend.

• Topher Grace, dancing the night away with his new girlfriend Teresa Palmer at a Klipsch Audio bash at Hollywood hotspot Les Deux. According to an onlooker, "Topher even did an impromptu dance for Teresa [and] she was hysterically laughing."

• Also at Les Deux several nights later: Masi Oka, enjoying his spot at a reserved booth with some pals. There to celebrate the launch of the EA Need for Speed ProStreet video game, the Heroes star stuck close to two women, whom he appeared to have walked in with, and even led one by the hand and kept her close to him as they were leaving. Another Hero on hand for the party: Hayden Panettiere.
