All the ladies were sipping white wine, except Dunst who drank a red-colored drink, according to an onlooker.
Dunst and Ronson were smoking, too, and lighting each other's cigarettes at their table on the patio at the famed West Hollywood hotel.
Between cocktails, they were picking at some food and sharing laughter as they told stories. Says an onlooker: "They were having the best time – being quite fun and quite playful." According to the onlooker, the group stuck around past midnight just "laughing the night away and being very carefree."
