• Fergie, jogging along the beach during her Mexican getaway with boyfriend Josh Duhamel. The Black Eyed Peas singer has also made time for plenty of R&R during her romantic trip.

• Lindsay Lohan, chatting and laughing with Paris and Nicky Hilton and several friends in a VIP booth at West Hollywood lounge Winston's. Lohan also had some special requests for the deejay: Olivia Newton-John's "Deeper Than the Night" and Pat Benatar's "We Belong." Also making the scene: Kimberly Stewart, partying at the other end of the bar with two girlfriends.

• Sacha Baron Cohen, trying to speak to his waiter in Japanese at Beverly Hills eatery Matsuhisa. Though Baron Cohen wasn't exactly fluent – he ended up communicating mostly through body language and hand signals – the waiter was amused. Despite all of the comedian's efforts, his friend ended up doing the ordering – in English. On the table: a cucumber roll and asparagus tempura.

• Nick Lachey, sharing a guys' night out with football-star pal Matt Leinart and other buddies at L.A. club Privilege. While various groups of women walked up to the table, Lachey and Leinart were too busy having vodka cocktails and catching up with each other to notice.

• Hilary Swank, looking very rested after leaving Ona Spa in Hollywood. The actress got an Environ facial, which she told the staff "was simply amazing," a source tells us. She also sipped on Goji juice, a berry drink that comes from the Himalayas. "She was in good spirits" – and left a generous tip, says the source.
