Nightlife staples Lindsay Lohan, Leonardo DiCaprio and Adrian Grenier, partying into the wee hours at SBar in Los Angeles. When Lohan arrived, in a red leather coat, the starlet made a B-line for Grenier's table, launching into a flurry of kisses and hugs. "It just looked friendly," an onlooker says of the affectionate greeting. And Lohan spent the rest of her night chatting with her friends. Meanwhile, a "mellow" DiCaprio enjoyed a guy's night out – augmented by one more pal when Grenier hopped over to his table to chat.
