PIVEN'S BANGIN' B-DAY
Yet another perk that comes with a hit TV show: "People actually come to you and say, 'Hey, can we throw a birthday party for you?' Instead of ruining your own home, you can ruin someone else's!" So says Entourage
star JEREMY PIVEN, who did just that (minus any house trashing) on July 23 to celebrate his 41st. Held at Malibu's Polaroid Beach House, the N9NE Steak House-catered fete featured mojitos and lobster tails and drew a fashionable and late LINDSAY LOHAN
, who managed three outfit changes—dress, bikini, bikini—despite arriving hours after most. Other guests included Piven's onscreen wife PERREY REEVES, KRISTA ALLEN and, naturally, an entourage (a number of whom he didn't even know).
Why is JENNIFER LOPEZ
smiling? The night before her 37th birthday, her husband, MARC ANTHONY, added a thoughtful serenade to his Houston concert set: With the audience backing him up, Anthony sang—what else?—"Happy Birthday."
HOLLY ROBINSON PEETE (above) hosted the Design-Cure benefit July 22 in L.A., which raised $600,000 for Parkinson's care and featured an Escada fashion show and an auction where SAMUEL L. JACKSON bid $15,000 for the Ultimate Boxing Package.
Dance fever! WILL FERRELL caught it July 21 in Miami: Getting down in the VIP section (and sometimes onstage) at Mansion, the actor danced only with his ever-present Corona—security guards warded off adoring female fans.
If blondes have more fun, then what do pinks have? In JENNY McCARTHY's case, a birthday blowout at the Vegas nightclub Jet for her sister AMY (above, left), who celebrated her 30th birthday July 22.
