• Reese Witherspoon, multitasking during a day out in Beverly Hills. The tank-top-sporting actress juggled a water bottle and her BlackBerry as she ran errands.

• Eva Longoria, giggling with a female friend over a dinner of fresh eel sashimi at West Hollywood restaurant Koi.

• Justin Timberlake, partying with Timbaland, Usher and Missy Elliott at Ghostbar in Dallas following his sold-out concert. The "SexyBack" singer worked the deejay booth and even did a little beat-boxing.

• Whitney Houston and Bobby Brown, having a family meal with daughter Bobbi Kristina at Mr. Chow in Beverly Hills. The trio ate shrimp fried rice and white prawns. "Whitney and Bobby were focused on their daughter," a diner told us. "(They) looked very comfortable and relaxed with each other."

• Bono, signing a guitar for a fan in the foyer of a Hooters restaurant in Hollywood. The U2 frontman, who wore one of his Gap INSPI(RED) T-shirts, obliged the axe-toting admirer's request and then was seated with two pals. A round of wings for everyone!
