Caught in the Act!| Cameron Diaz, Brooke Shields
• Brooke Shields, enjoying a sun-kissed carriage ride in New York City's Central Park with daughters Rowan, 3, and 11-month-old Grier. The actress spent quality time with her little girls during a break from filming her new TV pilot, Lipstick Jungle.

• Ashlee Simpson, snacking on guacamole and a taco platter with a female pal at Mexican restaurant Dos Caminos Soho – one of sister Jessica's favorite New York City eateries.

• Orlando Bloom, hunting for the nonfiction book Fiasco: The American Military Adventure in Iraq at Borders in Hollywood. The Pirates of the Caribbean star couldn't find it on the shelf and sought help from an employee, who brought a copy from the back. "By that time Orlando was on his phone," the employee tells us. "He hung up his call just to say 'Thank you.' It made my month."

• Eva Longoria, snapping up 10 pairs of sunglasses at the Solstice Sunglass Boutique at L.A.'s Beverly Center. With stylist and pal Robert Verdi by her side, the Desperate Housewives actress bought seven pairs of Gucci shades and three more pairs of designer frames – Valentino, Christian Dior and a pair of Marc by Marc Jacobs. Before leaving the store, Longoria grabbed a cleaning kit to keep her glasses streak-free.
