• She may be in Berlin for business to shoot racy ads for RICH Prosecco – but that doesn't mean Paris Hilton is skipping the club scene. The heiress hit up Maxxim Nightclub for a night of (pole) dancing for fellow clubgoers.

• Jennifer Aniston, offering a personal greeting to chef Nancy Silverton while dining at Hollywood's Osteria Mozza with a female friend. The actress approached the counter – where Silverton was prepping – and waved 'hello.' The chef reciprocated with a "virtual wave" since her hand was covered with flour.

• Lauren Conrad and Audrina Patridge,checking out the comic stylings of Jon Lovitz at West Hollywood’s Laugh Factory. While the Hills stars giggled at the show, they seemed more interested in chatting with each other, an onlooker says. Still, they shared a private meeting with the funnyman's manager afterward.

• Isaiah Washington, enjoying a cigar, solo, at West Hollywood's Chateau Marmont. The actor was dining with friends, but stepped away from the group to smoke.

• Zac Efron and Vanessa Hudgens, chatting and holding hands during the afterparty for Walk Hard at Social Hollywood. At the bash, the High School Musical stars were surrounded by A-list attendees, including John Mayer, who hung with a small crew of friends by a food spread. Also there: Knocked Up star Seth Rogen, Will Ferrell and a handful of former Saturday Night Live castmates.

• Sacha Baron Cohen, sipping pink grapefruit juice during a breakfast meeting with Jeffrey Katzenberg at the Four Seasons Hotel in Beverly Hills. The Borat actor, donning a grey Kangol newsboy style hat, even picked up the tab.
