• Drew Barrymore, heading back to her London hotel after dining with pals at trendy eatery The Ivy.

• Justin Timberlake, capping off a day of snowboarding at Park City Mountain in Utah by hanging out with an entourage of 15 people at Mexican restaurant Baja Cantina. Still clad in his boarding gear – a black North Face puffy jacket, cream-colored snowpants – the singer and his pals drank margaritas and snacked on chips and salsa. After about a half-hour, Timberlake and a few pals took off, just as the sun was starting to set over the mountain.

• Scarlett Johansson, chatting up Kirsten Dunst and Selma Blair during a night out at L.A. hot spot Hyde Lounge. "The trio of actresses were giggling, enjoying each other's company and bopping their heads to (the music,)" says a fellow reveler.

• Steve Martin, making the rounds at the Los Angeles Art Show at the Santa Monica Airport's Barker Hangar. Also checking out the artwork: Giovanni Ribisi and Barbra Streisand and James Brolin, who bought a $16,000 painting by artist Jeremy Lipking.

• Lindsay Lohan, having dinner with a female pal at L.A. restaurant Koi. On the table: an eel and avocado roll and Alaskan king crab legs in a miso ginger glaze. "She looked healthy," a fellow diner tells us. The actress, who's been in rehab since last week, has returned to work on the set of the thriller I Know Who Killed Me.
