A playful Sam Worthington
was ready for a guys' night out at new L.A. lounge Trousdale. Ordering beers and joking around with his friends, the Clash of the Titans
star pulled pranks and high-fived his pals – and his whole table was roaring with laughter. Though there were ladies surrounding his table, the Aussie seemed more interested in hanging with his male pals. Nearby, Kristin Cavallari
was happy to be the center of attention in her group of pals, greeting fellow revelers, like Jason Statham
, warmly with a hug.
After Monday's Dancing with the Stars taping, Cheryl Burke
, Derek Hough
, Nicole Scherzinger
and more returned to a favorite haunt,
West Hollywood nightspot Industry, for a fun night out. While Burke was dancing with her girlfriends, Hough and Scherzinger challenged each other to a dance-off. "They were so playful the entire night," a clubgoer tells us. "You can tell they really trust and respect each other." Also making cameos: Maksim Chmerkovskiy
and Evan Lysacek
Robert Downey Jr.
loaded up on jackets at the Belstaff flagship store in Rome – and he wasn't just shopping for himself. The Iron Man 2
star bought coats for his wife and son, and even wore the blazer he bought right out of the store.
and Sharon Osbourne
, dining at Morton's the Steakhouse in Woodland Hills, Calif., on a double date with his guitarist Zakk Wylde
and his wife. And the rocker stuck to steak, thank you, feasting on a prime rib, while his wife ordered a 12 oz. New York strip steak.
