Rocker Bon Jovi, and the Duff Sisters all were at Mr. Chows on the evening of May 2nd. Bon Jovi dined at the eatery as part of an American Idol post performance celebration. Hilary and sister Haylie Duff chose the establishment because it’s a good place to be scene. Out and about guy Lance Bass was part of the party crowd at Parc. Mischa Barton and underage player Rumer Willis got into Teddy’s. Bijou Phillips, Bai Ling and Justin Long were rappin’ with the paps and the fans outside of the Stoli party.
