It was a little bit Hollywood, a little bit rock ‘n’ roll at the 8th Annual John Varvatos Stuart House Benefit. What started as “a little party inside the store” according to the menswear designer, has now blossomed into a full-fledged extravaganza that blocks off Melrose at Robertson, where a couple of big tents hold a jam-packed kids’ section and a concert hall/silent auction/food and beverage central area.Over 1500 people gathered on Sunday to help fund Stuart House, a part of the Rape Treatment Center that focuses on helping children who have suffered sexual abuse, and many brought their own kids to join in the fun-filled afternoon. LL Cool J brought his kids, as did Omar Epps, Brooke Burke and David Charvet, Eva LaRue, Lauren Sanchez and the afternoon’s honorary hosts, Patrick Dempsey and Jillian Fink Dempsey. Dempsey, who sported a dark-blue suede jacket, admitted that he lusted after the rocker chic that was scattered throughout the party. “I wish I was a musician right now, they are all dressed in such great clothes,” he lamented. But he and the other beautiful Hollywood people on hand – James Van Der Beek, Jayma Mays, Justin Chambers, Julie Benz, Kevin McKidd, Sasha Alexander, Trevor Donovan, Melina Kanakaredes – may not have had the rocker chic going, but nor did they have their rough-and-tumble look either. On the other hand, partygoers Billy Idol, Glenn Hughes, Perry Farrell and rock photographer Mick Rock all looked like they’ve had more than a few hard nights on the road. But 49-year-old k.d. lang, who did a sublime set to close out the lovely afternoon, is apparently drinking from the fountain of youth. Her pink-cheeked skin matched her incredible vocals; she’s one rocker who hasn’t aged a bit.
