This weekend was a big one for house parties, launch parties and premieres, but celebs still managed to find time for charity! Jada Pinkett Smith, Jamie Lee Curtis, Jason Priestley, Wilmer Valderrama and Melina Kanakaredes were just a few of the stars attending the 15th Annual Dream Halloween by the Children Affected by AIDS Foundation in Santa Monica this weekend.

Our cameras also caught a bunch of cute kids, but when they're in costume, it's hard to tell who they are: child stars or celebrity spawn? (Check 'em out in the gallery below!)
