And they also know that stripes are sooo in this season!

Last night we spotted Hills hotties Audrina Patridge, Stephanie Pratt and Kristin Cavallari returning home from their Costa Rica vacay, and the ladies looked well rested and sun soaked as they made their way through LAX. I'm sure they had a blast on their getaway, but we definitely missed them, so we're glad to have 'em back!
