Miley Cyrus, dining with a female friend and an elderly couple at the Bazaar at the SLS Hotel in L.A. The group arrived (and left) in her SUV, and Cyrus was having a "blast and cracking jokes at the valet stand after her lengthy dinner," an onlooker says. The teen star was also "very friendly" and "interactive" with staff and restaurant guests.
Ashley Tisdale, enjoying some pampering with her mom and a girlfriend at the Nail Garden in Studio City, Calif. All three opted for an elaborate Minx nail job and the trio made an entire afternoon of it. "They were there for hours," a source says. "They were laughing up a storm."
The Fighter star Mark Walberg checked out the Narnia Ice Palace Exhibit at the Beverly Center in L.A. with his kids. While they didn't take any pictures with Santa, the family did go shopping at Toys 'R Us.
