New couple Avril Lavigne
and Brody Jenner
finished off their night with a stop at Voyeur in West Hollywood, strolling into the club hand-in-hand sporting matching black hoodies. The two headed right over to their booth, which was crammed with friends, and perched on the banquette, snuggling and sharing a few kisses. According to an onlooker, the two "acted like they were the only two in the club" and stayed out until closing time.
and hubby Marc Anthony
held court in the center of the room at Drai's Hollywood inside the W Hotel. The couple were surrounded by pals, including J.Lo's sister Lynda
, but Lopez danced up a storm and posed for pictures at the table. Still, the two were plenty affectionate with each other, holding hands, kissing and dancing together.
Robert Downey Jr.
had wife Susan Levin
by his side as he celebrated his upcoming Iron Man 2
with castmates Scarlett Johansson
and Don Cheadle
with dinner at Cache in Santa Monica, Calif. The group took over a private room where Downey was the star of the table, chatting up everyone and keeping his friends laughing. And of course, he was the star of the restaurant: At one point, the actor got up from the table and was instantly stopped by several female fans.
and Joshua Jackson
shared a dressed-down lunch at the casual Asian eatery Republic in New York's Union Square. In fact, the actress arrived wearing sweats! The two sat at a communal table and "quietly chatted," says an onlooker. "They were sweet and looked very comfortable with each other."
Dame Helen Mirren
and director husband Taylor Hackford arrived at the British Consul General's residence in L.A. for the champagne lunch for BritWeek. Hackford happily held his wife's purse as she posed for pictures and joked, "Sometimes she does still act like she is the queen," before the two went into the reception, smiling.
