• With girlfriend Bar Refaeli away in Spain, Leonardo DiCaprio hit up new nightspot Las Palmas with his usual group of guy friends, including Lukas Haas. With his hat pulled low over his eyes, the actor slouched down on the couch and got comfy, even propping his feet up on the table. Otherwise, he sipped a beer and played on his phone, focused on relaxing and kicking back – and ignoring the female clubgoers who would approach his table.

• Also enjoying a guys’ night out: Benji and Joel Madden. The brothers were enjoying dinner with friends at Katsuya Hollywood in a very large booth, and, an observer says, “It seemed as though they ordered everything on the menu!” Also at the sushi spot that night: Ciara, who ate in the private Dragon Room behind closed curtains, and Olympian Shaun White, who feasted on the restaurant’s signature dishes.

Jamie-Lynn Sigler, hunting for a birthday gift for her mother at Century 21 in New York City. “She picked up a bunch of colorful purses and beach bags,” an eyewitness tells us. And the actress seems to have been successful. After she left, she Tweeted, “Shopped @century21 today for a little downtown. Was packed like xmas! Got good stuff mom!”

• Also shopping: Nicky Hilton, who made a solo trip to Chagoury Couture, a new boutique in Beverly Hills, where she was hunting for a white dress to wear to the Cannes Film Festival. According to a source, she left the shop with several options.

Couples Retreat star Malin Akerman celebrated her 32nd birthday at Delphine inside the W Hollywood with a small group of family and friends, including actress Emmanuelle Chriqui. The casual group enjoyed cheese plates and seafood, and drank Chopin martinis – and even shared a birthday champagne toast.
